1991 Chevrolet Corvette

1991 Chevrolet Corvette Convertible — Teal over Saddle Tan, L98 V8, Clean Florida Car


Why This Car Is Special

The 1991 Chevrolet Corvette Convertible sits at an interesting point in C4 history. By 1991, GM had spent several years refining the fourth-generation Corvette that debuted in 1984, and the result was a car that was significantly more polished than the early C4 examples. The L98 5.7-liter V8 was producing 245 horsepower that year, a meaningful improvement over the output levels seen at the start of the C4 run, and the suspension geometry had been developed into a genuinely capable platform. The convertible body style, which had returned to the Corvette lineup in 1986 after a decade-long absence, was building a loyal following among buyers who wanted open-air driving without sacrificing the performance credentials that the nameplate had earned over decades.

What makes this particular 1991 Chevrolet Corvette Convertible worth a close look is the color combination and the condition of the structure underneath it. Teal — officially listed as Turquoise Metallic in GM's 1991 color palette — is one of the colors most associated with early 1990s Corvette production and has grown in desirability among C4 collectors precisely because it reads as period-correct without being common. Paired with the Saddle Tan leather interior and a matching tan convertible top, this car presents as a cohesive, well-thought-out combination from the factory. The undercarriage photos tell a story that matters more than color, though: the floorpans, frame rails, and structural crossmembers are solid and clean, which is exactly what you want to see on a car that spent its life in Florida rather than the rust belt.

Mechanical

The engine in this 1991 Chevrolet Corvette Convertible is the L98, a 5.7-liter V8 built around Tuned Port Injection. The TPI setup — identifiable by its distinctive plenum and individual runners visible in the engine bay photos — was designed to optimize low-to-mid range torque rather than top-end peak power, which made the L98 feel strong and responsive in real-world driving. Rated at 245 horsepower and 340 lb-ft of torque for 1991, it moved the Corvette from zero to sixty in the mid-six-second range, which was genuinely competitive for an American production car at the time. The 1991 model year was also the last for the L98, as the more capable LT1 arrived the following year. That transition point makes 1991 an interesting year to own — it is the final, fully sorted expression of the engine that carried the C4 through its first eight years of production.

Backing the L98 is the 700R4 4-speed automatic, which was the standard transmission choice for buyers who wanted the Corvette's power accessible without the involvement of a manual gearbox. The 700R4 is a well-understood, parts-supported transmission with a long track record in GM performance applications.

The suspension here benefits from an upgrade that the factory did not include: Bilstein shock absorbers. The C4 Corvette used a fiberglass mono-leaf spring arrangement front and rear, which was lightweight and effective, but the stock shock absorbers on high-mileage examples are frequently worn. Bilstein's monotube design is a well-regarded aftermarket improvement that restores and in some cases improves the original handling character. The undercarriage photos confirm that both front and rear Bilstein units are installed and visually intact. The undercarriage itself shows clean, solid structure throughout — no evidence of corrosion, patching, or prior accident damage on the frame rails or floorpan.
