Okay, got some catching up to do!
74 Cuda 360
Fair price, not a steal but not a rip off.
70 Cuda 440
Rip off. Don't get me wrong, that car is super sweet. And it looks to be about perfect - a high, high retail value for those cars is like ~$120K. $155K is well out of that ball park. I suspect it might sell though, if some rich collector happens upon it.
08 Shelby GT500
Fair price. It's perhaps a touch high, I would try to negotiate it down a couple $K. But that's certainly in the ballpark.
02 True Blue GT
Unfortunately for him way Rip Off. A normal 02 GT vert is in the $5K range. His is more than double that. I understand a lot of work was put in to it, and that it might we well loved and cared for. But you never get back what you put in. No one wants to buy a $12K 02 GT. (Sorry if it's someone's car here
Nice work though! )
94 GT 331
Same as above - Rip Off, but only because you don't get back what you put in. Tack on that it's a salvage title, and ugh. And the guy knows nothing about it, just basically passing it on. That will be a really tough sell. Lots of nice mods - but again, like above, who wants to spend $10K on a 94 Mustang??
