The 1987 Chevrolet Corvette marks a fascinating sweet spot for enthusiasts and collectors diving into the Fourth Generation (C4) of America’s sports car. While the early C4s (1984–1985) are often criticized for their harsh ride and teething problems, and the later LT1 models (1992–1996) command higher premiums, the 1987 model year represents the moment the platform truly matured. If you are scouring the market for a 1987 Corvette for sale, you are looking at a vehicle that introduced significant mechanical refinements that made it faster, more reliable, and much more pleasant to drive than its predecessors.

Searching for a classic car from the late 1980s requires more than just a checkbook. It demands an understanding of the specific engineering quirks of the era, the shifting market values for different trim levels, and a keen eye for the aging electronics that defined the "high-tech" interior of the time. This analysis breaks down everything a potential buyer needs to know before signing a title.

The Heart of the Machine: L98 V8 and the Roller Lifter Revolution

When you open the clamshell hood of a 1987 Corvette, you’ll find the 5.7L L98 V8 engine. While this engine was introduced in 1985, the 1987 version included a critical upgrade: the transition to hydraulic roller lifters.

This mechanical change might sound like a minor detail, but it had a significant impact on performance and longevity. Roller lifters reduced internal friction and allowed for a slightly more aggressive camshaft profile. As a result, the factory horsepower rating bumped up to 240 hp, with a massive 345 lb-ft of torque. In the context of 1987, these were world-beating numbers for a mass-produced V8, allowing the Corvette to out-muscle many contemporary European rivals.

The Tuned Port Injection (TPI) system is the visual centerpiece of the engine bay. Its long intake runners were designed to maximize low-end torque, giving the car a "point-and-shoot" character in city traffic. However, in our testing and historical experience with these units, the TPI system tends to run out of breath above 4,500 RPM. This makes the 1987 Corvette an incredible cruiser and a monster off the line, but it isn't a high-revving track star in stock form.

Navigating the Transmission Options: 700R4 vs. the Quirky 4+3 Manual

If you find a 1987 Corvette for sale, it will likely be equipped with the 700R4 4-speed automatic transmission. This was the most popular choice at the time and remains a robust, relatively easy-to-service unit today. However, for those seeking a more engaging experience, the "Doug Nash" 4+3 manual transmission is the alternative.

The 4+3 is one of the most unique transmissions in automotive history. It is essentially a heavy-duty 4-speed manual gearbox paired with an electronically controlled overdrive unit on the top three gears.

Understanding the 4+3 Manual

In practice, this setup provides seven forward speeds, though it functions primarily as a 4-speed with high-speed cruising efficiency. The overdrive unit requires its own dedicated maintenance, including regular fluid and filter changes, which many previous owners neglected. When inspecting a manual 1987 Corvette, it is vital to ensure that the overdrive engages and disengages smoothly via the button on the shifter. A failed overdrive unit can be expensive to rebuild, often leading owners to swap in a later 6-speed ZF transmission—a modification that may affect the car's collector value.

The Reliable 700R4 Automatic

The automatic is generally the safer bet for a "driver-grade" vehicle. It features an overdrive 4th gear that makes 70-mph highway cruising quiet and relatively fuel-efficient (often reaching 22-24 MPG on long trips). When testing an automatic, check for firm shifts. If the transmission feels "slushy" or hesitant to downshift under throttle, it may be a sign of a failing TV (Throttle Valve) cable adjustment or internal wear.

Suspension Tuning: Z51 Performance vs. Z52 Sport Handling

One of the biggest complaints about the 1984–1986 Corvettes was the bone-jarring ride quality, especially on cars equipped with the Z51 performance package. For 1987, Chevrolet responded by introducing the Z52 Sport Handling Package.

The Z51 Package: Track Focus

The Z51 was designed for autocross and track enthusiasts. It featured heavy-duty springs, larger stabilizer bars, and a faster steering rack (13:1 ratio). While it handled like it was on rails, the ride was notoriously stiff. Finding a 1987 Corvette with the Z51 package is a win for collectors, but be prepared for a physical driving experience.

The Z52 Package: The Sweet Spot

The Z52 package was a revelation. It incorporated many of the Z51's upgrades—such as the oil cooler, heavy-duty radiator, and larger 16-inch wheels—but utilized softer springs and shocks. This resulted in a car that could still pull nearly 0.90g on a skidpad but wouldn't rattle your teeth loose on a potholed road. For most modern buyers looking for a weekend cruiser, a Z52-equipped car is the superior choice.

Interior Technology and the Atari Digital Dash

The interior of the 1987 Corvette is a time capsule of 1980s futurism. The centerpiece is the liquid crystal display (LCD) instrument cluster, often nicknamed the "Atari Dash." While revolutionary at the time, these units are a common failure point after nearly 40 years.

Inspecting the Digital Gauges

When you turn the key, the entire dash should illuminate with vibrant oranges and greens. Common issues include:

  • Fading or "Sunburned" Displays: The polarizing film on the LCDs can degrade due to UV exposure, making the gauges unreadable in direct sunlight.
  • Failed Backlighting: The cluster uses several halogen bulbs that get very hot. Over time, the heat can damage the internal circuit boards.
  • Grounding Issues: If the dash flickers or displays nonsensical data, it is often a sign of a bad ground wire near the steering column or engine block.

A professional rebuild of a digital dash can cost anywhere from $400 to $800. If the 1987 Corvette you are looking at has a dark or flickering dash, use that as a major negotiating point.

The Bose Gold Audio System

Many 1987 models were optioned with the Bose Gold sound system. While high-end for its time, these systems use individual amplifiers located at each speaker. These amplifiers are notorious for failing, resulting in popping noises, static, or complete silence. Many owners replace them with modern head units, but if you want to keep the car original, you will likely need to send the amplifiers out for a capacitor replacement.

Body Styles: The Return of the Convertible

After an 11-year hiatus, the Corvette convertible returned in 1986, and by 1987, it was in full production. 1987 was also the first year the convertible was available in all standard colors.

Coupe vs. Convertible

The coupe features a "Targa" top—a removable roof panel that can be stored in the rear hatch area. This gives you an open-air experience with the structural rigidity of a fixed-roof car. The convertible, however, offers the classic roadster silhouette.

Because the C4 was designed from the ground up as a targa/convertible, it lacks a traditional roof structure. This leads to "scuttle shake"—a noticeable vibration in the steering wheel and dashboard when driving over rough surfaces. The convertible is slightly more prone to this than the coupe. When inspecting a convertible, pay close attention to the condition of the folding top mechanism and the weather stripping. Replacing the rubber seals on a C4 is a tedious and expensive task, often costing over $1,000 for a full kit of high-quality EPDM rubber.

Rare Finds: The Callaway Twin Turbo (RPO B2K)

For the buyer with a significantly higher budget, 1987 was the first year for the Callaway Twin Turbo Corvette, available directly through Chevrolet dealers under Regular Production Option (RPO) B2K.

This was the only time in Corvette history that a non-GM performance package was given its own RPO code and a full factory warranty. These cars produced an astounding 345 hp and 465 lb-ft of torque. Only 188 were produced in 1987. If you encounter a genuine Callaway 1987 Corvette for sale, expect the price to be triple or quadruple that of a standard model. They are highly sought-after collector pieces that bridged the gap between the standard Corvette and the later ZR-1 super-Vette.

Pre-Purchase Inspection Checklist

Before you head out to look at a 1987 Corvette for sale, print this list of common "deal-breakers" and maintenance items:

  1. VATS (Vehicle Anti-Theft System): The 1987 model uses a pellet-key system. If the car won't start and the "Security" light is flashing, the ignition cylinder or the key pellet is likely worn out. This is a common issue that can leave you stranded.
  2. Headlight Motors: The iconic pop-up headlights use plastic bushings that eventually crumble. If the headlights "wink," make a grinding noise, or refuse to open, you’ll need a $20 rebuild kit and a few hours of labor.
  3. Cooling Fans: These cars run notoriously hot (often reaching 228°F before the secondary fan kicks in). Ensure the fans work. Check the area between the radiator and the A/C condenser for debris; it’s a "vacuum cleaner" for leaves and road trash, which can cause overheating.
  4. Weather Stripping: Look for cracks around the windows and the rear hatch. Water leaks in a C4 aren't just an annoyance; they can destroy the expensive electronic modules hidden under the carpeting.
  5. Tires: The original 16-inch wheel size (255/50R16) is becoming increasingly difficult to find. Major manufacturers like Goodyear and Michelin have largely discontinued this size. You may be limited to specialty brands like BFGoodrich or forced to upgrade to 17-inch wheels from a later C4.
  6. The "Clunk": During a test drive, listen for a clunking sound from the rear when shifting between Drive and Reverse. This usually indicates worn U-joints on the half-shafts—a relatively simple but necessary fix.

1987 Corvette Market Value Analysis

The market for the 1987 Corvette is currently stable, with slight appreciation for low-mileage survivors. Based on recent auction data and private sales, here is what you should expect to pay:

  • Project Condition ($3,000 – $6,000): These cars usually have high mileage (over 120k), faded paint, and interior issues. They may need a transmission rebuild or a digital dash repair. Only buy in this range if you are a capable DIY mechanic.
  • Driver Quality ($8,000 – $13,000): This is the most common range. You can expect a car with 60,000 to 90,000 miles that looks good from ten feet away. It should have a functioning AC and a decent interior, though perhaps some minor mechanical needs.
  • Collector/Show Grade ($15,000 – $22,000): These are low-mileage (under 40k) "time capsules." They often come with original documentation, window stickers, and pristine leather interiors. Red/Red and Black/Black color combinations command the highest prices here.
  • Callaway Twin Turbo ($50,000 – $85,000+): As mentioned, these are specialized collector vehicles. Price depends heavily on the specific build number and documentation.

Why the 1987 Model Year is a Smart Investment

Investing in a 1987 Corvette for sale is often smarter than buying an '84 or '85. You get the improved engine internals, better seats (introduced in '86), and the refined Z52 suspension option. It is a car that can be comfortably driven to a car show three hours away, enjoyed on a twisty backroad, and maintained in a standard home garage with basic tools.

While it lacks the sheer raw power of the later 300-hp LT1 cars, the L98’s torque makes it feel faster in daily driving situations. Furthermore, the 1987 model avoids some of the more complex electronic engine management systems found in the 1990s models, making it a favorite for those who prefer "analogue" mechanical work.

Frequently Asked Questions

Is the 1987 Corvette reliable?

Mechanically, the L98 engine and 700R4 transmission are extremely robust and can easily exceed 150,000 miles with basic maintenance. The "unreliability" associated with the C4 usually stems from aging electronics (dash, Bose amps, VATS) and rubber seals rather than the drivetrain itself.

Can I use modern oil in a 1987 Corvette?

Because the 1987 engine uses roller lifters, it is less sensitive to the lack of ZDDP (zinc) in modern oils compared to the 1984–1986 flat-tappet engines. However, using a high-quality synthetic 5W-30 is still recommended to keep the TPI system clean and the engine protected.

What is the best color for resale?

"Bright Red" (Code 40) is the quintessential Corvette color and generally the easiest to resell. However, "Copper Metallic" is exceptionally rare for 1987 (only 87 produced) and can command a significant premium from serious collectors.

How do I check if it's a real Z51 or Z52?

Look for the RPO sticker (usually located under the center console lid or in the storage compartment behind the seats). Look for the codes "Z51" or "Z52." If the sticker is missing, you can check for the heavy-duty cooling components and the steering rack ratio, but the sticker is the only definitive proof.

Summary

Finding a 1987 Corvette for sale offers a unique opportunity to own a piece of 1980s history that still delivers a modern-feeling performance envelope. By focusing on cars with documented maintenance, checking the health of the digital dash, and choosing the right suspension package for your needs, you can secure a classic that is as rewarding to drive as it is to look at. Whether you choose the high-torque L98 coupe or the sun-drenched convertible, the 1987 model remains a standout year in the Corvette's long and storied legacy.
