Check
this auto thats currently on the Ebay auction block. It appears to be in good condition, has very little mileage and if this is indeed a true buy, the "Buy it now" price is pretty reasonable considering is one of the most freaking rare cars of the 90s if not of at least several decades. Which brings me to one other thing, I never knew they made them back in 1973.
Btw, did you know the engine used in that is the same as the one used in
this Group B rally car, but twin turbocharged? Here is another source about
that rally car and more.
