I was just checking out audi's on ebay and came across the wrecked A8.

Anyway, its only at 1500 right now and you get the entire car, so it would be a good donor vehicle, then you could probably make the money back by selling parts of the car if it goes for a good price. I think this engine makes 300hp and has 5 valves per cylinder and variable valve timing and a 5 speed tiptronic transmission.
