What are these x brands worth?

$3k on the chevelle is fair,maybe a bit high. I think $10k is really high for that bird convert. In this market, I don't know anyone that would pay that. Last year we sole a 67 GTO convert, numbers matching 326 4spd A/C car in a little worse shape for $7k. I would say $5-$6k on the bird. Both are cool cars and I wish you luck on the purchase, but remember that right now is not the time to sell. Cars are going real low. My friends TX9 V code R/T SE Challenger that is done and runs and drives got bid up to $31k. This is for a nice car. We still have a yard full of cars that we can't sell, soon they will be worth more just to take to the scrap.
