I see that Steve Gray at Brooklands is half way to completing both an A98 Coupe from scratch and a racing version. Both are out of aluminium and one appears to be based on a later chassis while one is virtually identical to the original. I here that he is using the Roush engine and Aston Martin Vanquish box with the manual coversion. When I was there, one was half way complete with the body buck sitting next to the car and the work being transferred off the buck as he progresses. With that Roush V8 it will be nearly twice the BHP of the original!!!
Can't wait to see these cars finished. They should have been built years ago.
