How much do you have into your 74 and how much would you need to throw into it to get it to the point you'd like? And what are the known issues that absolutely need to be repaired?
I bought the car years ago as a present to myself for graduating college and landing a decent job, I Was originally looking for a duster or a demon because here in Canda the prices of e bodies were just too high. However on my way to go look at a so-so demon I found this Challenger near a buddies cottage. Took it for a test drive couldn't wipe the smile of fmy face, so I negotiated him down to 14k. To me that money is gone and I don't feel bad it felt like the best 14 grand I ever spent.
Since I have owned it I have done some stuff to make it reliable , complete new fuel system (carb to gas tank, lines, filters pump, everything), complete new cooling system, complete new brake compnents (lines, rubber ines, slave cylinders pads, master cylinder and everything), New exhaust system and headers, regular maintenance stuff like plugs, rear main seal, plug wires, distributor, old style looking AGM battery, repainted the engine in corporate blue, bought a restored 360 air cleaner housing, put a few decals back on it. put in a sweet 8 track player!
But in my eyes none of that raises it's value.
What is gong on it is the body, it needs some floor pan work, the front fenders are fiberglass, the rear fenders are half fiberglass, the rockers look like the surface of the ocean, the doors need attention, couple of small bubbles under the vinyl top and all the previous body repairs look like they were done by someone in thier garage. I predict the body will put me out more than I even paid for the car. If the calendar contest is still up it's the purple 1974 challenger, it's easy to spot it's the only one taken from the back of the car.
Hence my question sell my car in today's market for ~12-14k? give it a partial driver quality facelift for 20-25k and never really see any of it back but at least have a car that is solid and i can upgrade it as I want from that point.
