1991 C4 Corvette ZR-1 Values
As of June 2023, the appraised value of a pristine 1991 ZR-1 Corvette is $67,300. This figure refers to Condition #1 vehicles, which are deemed to be the most superior in terms of aesthetics and quality. They possess a magnificent visual presence with gleaming painted and chromed surfaces that resemble mirrors. Not a single speck of dust is allowed, and the materials used are always correct and immaculately installed. To summarise, Condition #1 vehicles are nothing short of “concours” quality.
The prices for cars in excellent, good, and fair condition respectively are $41,100, $20,600, and $16,700. Additional value can be obtained with the inclusion of a glass roof on the coupe (+$500) or a hard top on the convertible (+$1,000). If opting for an automatic transmission, expect a 10% deduction.
Value of the 1991 Corvette Coupe and Convertible
The base 1991 Corvette coupe ranges from $27,000 in #1 condition to $4,800 in #4 condition. The base coupe ranges from $32,600 in the #1 condition to $6,500 in the #4 condition. (These values are as of June 2023)
1991 Chevrolet Corvette Callaway Value
The 1991 Chevrolet Corvette was the last year of the B2K Callaway Twin Turbo Corvette option. This option was an additional $33,000. The cars were able to reach up to 450 horsepower in later models after being sent to Callaway Engineering. However, 1991 was a relatively low year in sales for the C4 Corvette, with just 20,639 units sold and only 71 Callaway Corvettes were produced. Because of this rarity, these models can command a high price and significant premium in value.
With only 27 models produced, the 1991 Chevrolet Corvette Callaway 2dr Coupe 8-cyl. 350cid/403hp Twin Turbo is an incredibly rare car. According to June 2023 data, it holds a value of #1 Concours at $55,800, #2 Excellent at $36,500, #3 Good at $26,800, and #4 Fair at $13,500.
The 1991 Chevrolet Corvette Callaway 2dr Convertible 8-cyl. 350cid/403hp Twin Turbo has a current estimated value of $64,800 for #1 Concours condition, $50,700 for #2 Excellent condition, and $31,100 for #3 Good condition. Of note, only 44 Callaway Convertibles were produced in the 1991 model year.
For four years, the Corvette offered the Regular Production Option B2K or the Callaway Twin Turbo conversions. On September 26, 1991, the 500th Twin Turbo conversion was completed by Callaway, and they continued on to make twelve more cars with special badging and options. These vehicles are better known as the Callaway 500 Series cars or Speedsters due to their custom open-body design by Paul Deutschman. These Callaway out-powered the ZR1 by boasting 400 horsepower and 580 lb-ft of torque in comparison to the ZR1’s 375 HP and 370 lb-ft. Even more impressively, the Speedsters reached a peak of 450 HP and 613 lb-ft of torque. Referred to as the “Mini Sledge” in reference to the famous Callaway Sledgehammer. It featured the Speedster body, O.Z. 3-piece racing wheels, and special 500 Series badges on the dash and driver’s side intercooler.
