Mach 1 w/replaced engine?

It says the engine was replaced under factory warranty, so if it was a legit engine problem that needed replacing, I myself would'nt be sweating it, but I would definitely want to see some kind of paperwork showing the problem that it had for needing replacing. It's a non-IUP Mach (No interior upgrade package, the only option other than manual or auto transmission.) Looks good, and $19,900 is'nt a bad price at all considering it's a dealership.
 
yeah, like others said, make sure you have paperwork showing it. My 2003 Mach 1 had an oil pump failure while I was on a freeway. The dealer replaced it under warranty and I made sure that paperwork was with the car when I sold it to CarMax
