Some Trivia…

1991 was the last year for the Callaway twin-turbo option, selling 62 units at $33,000 each.

1991 introduced a new turbine wheel design that was used through the 1996 models with only minor differences in finish.

1991 Corvettes got the rear end look from the 1990 ZR-1 including the rectangular taillights. 1991 had restyled side louvers, front cornering/parking lamps featured a wraparound design.

Further changes were made the following year in 1991, including extra ZR-1 badges on the fenders and the introduction of Acceleration Slip Regulation (ASR) or traction control.

The 1991 Corvette convertible top is made of canvas or vinyl depending on the color that was selected.

The optional black-finished luggage carrier is functional as well as good-looking.
