We would be willing to donate a 1990 Audi V8 Quattro for this event.
The good:
We already have the car here
it runs (with a little work) needs power steering lines, ac comp, belt, fuel filter, distributor (have all those)
it drives (with more work) needs front struts installed, a rear diff installed (have those)
we have 90% of the parts to make it runable
The bad:
It needs alot of wrench time to get it back going (a solid weekend) as it is partially stripped
I don't have the time to do all the wrenching myself, I will need help.
this will make the monetary requirements much easier to deal with.
Hopefully even if we don't use this car we can get something going.
