One-Family-Owned 1974 Chevrolet Corvette Convertible 454 4-Speed

Description

Introduced as part of the C3 generation’s later evolution, the 1974 Chevrolet Corvette was the first to feature both front and rear impact-absorbing urethane bumpers and the last to be fitted with a big block engine option.

One-family-owned since new, this 1974 Chevrolet Corvette Convertible is finished in Bright Yellow over tan upholstery. The car was fitted with a 454ci V8 from the factory, paired with a 4-speed manual transmission plus a black convertible soft top and color-matched removable hardtop. Professional photos included in the gallery come from a feature in Corvette Magazine, a copy of which accompanies the sale.

Presented by the seller as a largely original example that was said to have been used as a daily driver through the early 1990s, this C3 sits on 15” Rally wheels and has been fitted with a smaller diameter steering wheel and aftermarket stereo system. Highlights from the most servicing said to have been completed are mentioned below.

This 1974 Chevrolet Corvette Convertible is now offered with a color-matched hardtop, various spare parts, the removed factory radio, a copy of the Corvette Magazine feature, and a clean California title in the seller’s name.
