After noting that Keiths 86 and the two 86 prototypes in HOTB have license plates in the same range I decided to see if I could find any more. Using the UK Carfax site Autocheck I began hunting them down. It appears that there were at least 5 Corvettes within +/- 20 license plates.
Here is what I found:
D123FPW Chevrolet Corvette, Red, Manual, 2 Door Saloon, Petrol
D131FPW Chevrolet Corvette, Yellow, Manual, 2 Door Saloon, Petrol
D137FPW Chevrolet Corvette, White, Manual, 2 Door Saloon, Petrol
D138FPW Chevrolet Corvette, Grey, Manual, 2 Door Saloon,Petrol
D142FPW Chevrolet Corvette, Gold, Manual,2 Door Saloon,Petrol
The two bold listings are Corvettes that are unknown.
