I just bought a 1974 Spitfire 1500 today for 1,000 US. I think the power train is good, with a few tweaks. As the car resides in the midwest, I expect a fair amount of rust, although curiously, the driver's side floor pan seems solid. It's also red while the car's original color and current color seems to be green. Am I correct in assuming this pan was fitted from a donor car and is not likely the original pan? I had a 1978 Spitfire when I was much younger so I'm excited about the chance to put this one back together.
