Seriously, around here, if not an LT1, it would be lucky to bring 9K in excellent shape... Usually runs by the years on the regular vettes. Except pre 1971...they can bring more. But after 70, a 71 is usually in the 7100 dollar range, and it goes up....76 is 7600 dollars and so on...unless they are rare like the LT1 or a Pace Car...something on that order...good luck...and yes, the frames will rust on some of those 70's models...
