Don't really see the comparison logic with the Tahoe, will he be driving this T/A as a daily driver? Compare it to other collectable commodities like a Boss 302, or a Z28.. LOL 20 to 25K would be a good buy if its all numbers matching and block is a numbers T/A with the original carbs etc.. but if the block is not or if missing the intake ,carbs,cleaner and some of the other "little" stuff it quickly turns into a average or not so good deal. I understand the excitement of the "FIND" but this cars value is in the details.
