As much as I like the classic mustangs I wouldnt trade it because of all the stuff thats on your car thats just me
Nope. A "clean" 66 usually involves rust somewhere that you just didn't know about, until it becomes a structural issue, or something you need to address.
Can't answer you until you tell me more... 1) What are you going to use the car for? Daily driver? Weekend toy? 2) Is it a straight trade, or cash difference? How much, which way, etc. 3) Like StangGT1995 said, is it really "clean"? Check the floors, rear frame rails and torque boxes, trunk drops, inner fender aprons, rear quarters for rust (or bondo repair). 4) Have you driven it? Are you happy with the way it drives? I much prefer 1st Gen stangs to Fox bodies, but there's a world of difference in how they drive out. 5) Is it front drum brakes? If you haven't experienced brake fade with front drums, take it for a test drive, warm them up real good, then do an urgent stop--just make sure you've got room on both sides when you do! If you're asking "what's it worth?", we need to see pics, and know more about the car. If you're asking "what should I do?", only you can really answer that. We can help you by telling you the +/- of a vintage (I assume you know them for your car), but in the end, you gotta decide what will make you happy.
Its gonna be my weekend car. Got a truck. And Ive been looking at it and there is no rust or signs of it except There is a tiny bit of it on the passenger door but thats all I found. Interior is new.... Ok paint job and runs good. even trade
Underneath is rust-free also? The cancer is worst in the places that are hard to see (the ones I listed above). If it's truly rust-free, I'd say you've got a pretty fair deal. Not sure what your car is worth, but depending on where in the US you are, the 66 is probably worth$5-8k. Given what you described, I'd trade, but I'm not a big fan of Fox bodies, so I'm certainly biased.
