It's a great car show, and I highly recommend everyone to go and take in the festivities. As far as buying, I think I'd say "don't", unless things change this year.
I went to buy a 70 Chevelle, year before last, and had about 80K to spend. I really did my homework, and thought I would be close to the money.
"I never got my hands out of my pockets." Stupid money, bought a nice car, but way over market value. Now the Chevelle (as well as many muscle cars and Corvettes) market has softened, and many profiteers are in way to deep.
I am hoping that with all of the lawsuits, and bad PR that BJ has had, that more buyers will come to their senses. The schill biding and back office goings on, aren't secrets any more.
