Take a look on this one, just found on Racingjunk: http://www.racingjunk.com/category/1471/Other/post/1697907/1964-Buick-Riveria.html Dual quad car in nice condition for 8500$, I wish I had found a car like this two years ago, when I was looking for a first generation Riviera. :TU:
I had the car inspected several months ago by a fellow board member, the car does not appear to have an X code engine and I don' think it was numbers matching. Also has some rust issues and is nicer in the pics than in person. The owner bought it several years ago at the Leake auction and hasn't driven it much at all since buying it, doesn't know much about the car. Real nice guy though.
