I also tried an rv8 and thought it an oddity. Just bunginging very thick seats in a space too small made for a hideous driving position as Dave says. I had a sneaky liking for the rear wings though, sort of Bentley lines I thought. In the end I went for an older v8gt as no Costello ones to be found at that time. It was a good car, proper sound, good straight line performance and immensely comfortable even though the seats looked very crude, they were really good. An all day driver alright.
Sold it in the end to the owner of NG cars, I think he was going to rebuild it.
