Probably more of a classic than a Challenge contender so I'm going to post this here as well.

1981 Lancia zagato also known in Europe as beta Spyder with only 28,000 original miles on it.
About 99% of people who see this will have no idea what this car is...
Not perfect, but no rust. Just a little bit here and there and you'll have a show car.
It's silver with a black interior. However it will need a new soft top, and probably to have the original paint redone. The car needs very little, but you could enter it and any car show next any Ferrari. It's just so rare. It needs to go to a good home. I have original manuals and a lot of documentation for it.
I'm pretty sure this would look good in the Suddard stable.
