Overview

The 1987 Chevrolet Corvette is a two-door, two-seat American sports car from the C4 generation, designed for drivers who want classic V8 performance with sharp 1980s handling and a low, aerodynamic profile. It sits as a relatively attainable collector-performance option in today’s market, often appealing to enthusiasts who want a weekend car that still feels modern enough to drive regularly. For 1987, the Corvette continued the C4’s focus on improved chassis tuning, fuel injection drivability, and daily-usable performance. Buyers typically cross-shop it with other 1980s performance icons, but the Corvette’s parts availability and large enthusiast support make it especially appealing.

Key Features

1) 5.7L V8 power: The 1987 Corvette uses a 5.7-liter (350 cu in) L98 tuned-port injection V8, known for strong low-end torque and good street manners for its era. 2) Transmission choices: Many 1987 models came with a 4-speed automatic (with overdrive), while manuals were available depending on configuration, giving buyers a choice between easy cruising or more involvement. 3) Lightweight sports car layout: A low-slung body, rear-wheel drive, and a performance-focused suspension make it a genuine handling car, not just a straight-line cruiser. 4) Classic C4 cockpit and ergonomics: The C4 interior emphasizes a driver-focused dash and a deep seating position, which many owners consider part of the Corvette’s signature feel. 5) Strong aftermarket and community support: From suspension refresh kits to ignition and cooling upgrades, 1987 Corvettes benefit from a huge supply of replacement parts and knowledgeable specialty shops.

Common Issues & Reliability

For shoppers researching 1987 Chevrolet Corvette reliability, the good news is the L98 engine is widely regarded as durable when maintained, and many cars reach high mileage. However, age-related issues are common, and neglect can turn “small problems” into expensive repairs. Here are some 1987 Chevrolet Corvette common issues frequently reported by owners: 1) Digital dash and instrument cluster glitches: The C4’s electronic display and related circuitry can suffer from dimming, intermittent readouts, or complete failures. Problems often show up with age rather than mileage, commonly appearing on cars in the 60,000–120,000 mile range depending on storage conditions and electrical health. 2) OptiSpark-style ignition concerns are not typical for 1987, but ignition and sensor issues still happen: On the L98, owners more commonly report distributor/ignition module wear, aging plug wires, and sensors (like coolant temp or throttle position) causing rough idle or drivability issues, especially as mileage passes 80,000–120,000. 3) Cooling system wear and overheating risks: Old radiators, tired fan motors, failing thermostats, and degraded hoses can cause heat-soak and overheating—especially in warm climates or stop-and-go traffic. Many cars need cooling system attention by 70,000–110,000 miles or sooner if maintenance history is unknown. 4) Weatherstrip leaks and interior squeaks/rattles: Door and hatch seals can shrink and crack, leading to water leaks, wind noise, and musty odors. This is one of the most common “1987 Chevrolet Corvette problems” complaints because it impacts comfort even when the drivetrain is healthy.
