Since warranty was brought up: Forget the 30 day 50/50 warranty from a used car dealer. Back in the 90's when I was a mechanic at a Honda dealership, the older high mileage vehicles they sold came with a 30 day 50/50 warranty. We wouldn't work on non Honda vehicles. The 50/50 warranty work was always sent to a specific garage in a ghetto part of town, Cleavland Ave in Columbus, OH. That specific garage was cheap to begin with but fubbed the numbers in our favor. I remember hearing of a customer spending $800 getting a new head gasket and the head resurfaced on a Nissan Sentra 20 years ago.
