Hey, i got a question... The mustang which i may buy is salvaged. its a 95 mustang gt w/ 31k miles on it, i was going to be buying it for $4k. everything was repaired and its my dad's bestfriend's car. so i know the history of the car and all and that it was done by a professional. But anyway, im wondering the engine is a little rusty, im thinking maybe its because it was sitting outside threw a few michigan winters with a bent up hood. Before buying i want to make sure it is the original engine that came in the car. Any way that i can check by serial number? I'm also going to do a compression check, but i know that may not be all that accurate. When doing the compression check any idea what the results should read?
