I've been looking for another alternative to the PRV and found some Canadian speedshops that work on the PRV, more importantly there is a shop in Germany that stocks Alpine 310 engines and has the mods necessary to create full-blown a610 Delorean supercars....just thought i'd try to contribute to the group. the shop is called Simon- auto...if i can figure out how to post the link I will. Ahh the possibilities...i'd love to toss this particular Viper a beating, and still have paid less and done it with the "beautiful relic" he's dubbed my car.
