i think the Value of a car is also, what you do NOT have to do to it. If the Motor is OK (GET IT CHECKED out by a Mechanic!!) the Trany is good, Tires, Glass, Wiring should look Good and Not Messed with. Look at it on a hoist too, check it really good for Rust. If all is OK, I think 23k is Not a bad Buy. IF you need to do an overhaul, You could spend 5k on everythink to do it, , so Just Considier everything. If The Car could be improved with only a Nice paint job , it would certainly be an invistment, and improve the Value too. I have had Two Barracuda's one with a 318, but I did put a 340 in it, which greatly improved the resale. good luck
