I know that the V8 450 SE/SEL/SL cars from 1975-76 are not coveted because of the location of the catalytic converter - it's under the hood, and they got real hot, could fry the wiring, cause underhood fires - that issue was fixed in 1977 when the cat was moved downstream

You should verify the location of the cat before making your offer on this car, if the car has the cat under the hood I would be inclined to pass on it for that reason alone.

To me that would be the threshold question, if it passes that test, then I would be OK with checking out the car further, having it inspected, checked for rust. For $3000 it had better be AWFUL nice, near to perfect.
