Thanks for all your help and sorry about the delay, my room got moved around and comp was down for a few days.
First of all, it is a car at a dealership, comes with a warranty (3 month/3k mile unlimited) and has extended warranty available (1-3 year). I saw the carfax report, clean title, 2 owners, both of which in my state, no accidents, looked good. My dad and I have both checked out the car, he verified that it was clean inside and out, as well as underneath the car. I went in the next day and had a look at it. The engine bay is, as far as I can tell, completely stock. Ford and factory stickers abound, it is remarkably clean, you honestly would think it just rolled off the line no more than 1000 miles ago. I forget the exact brand of oil filter, but it was white, so I'm going with either Motorcraft, K&N (which I think it was) or Cummings.
The test drive was fun, if not slightly on the side of making me nervous. For one, I hadn't driven stick in awhile, so I was praying I wouldn't stall ot (which I didn't until I parked it afterwards). Checked the AC, didn't leave in on the whole time, it was rather cold to begin with. Checked radio in the lot, then left it off for the remainder of the drive. Power seat works, as well as the cruise control. Smooth ride, quiet inside, and actually had power to it (The transition from a 2.3 auto to a 5.0 Manual is fun) something I'm not used to. At any rate, I didn't drive it very hard since I was still adapting to the manual, but I took it on the highway and had no trouble hitting 75, and then on the off ramp decided to open up some more. That didn't last too long because I hit 5 over the limit (55 from 35) within a second, so I was impressed. On a side note, maintaining 75 mph at ~1500 RPM was a decidely interesting experience.
As it stands, my dad is highly recommending that I buy the car, so the biggest thing now is insurance and other such details. Can anyone suggest anything else I check for?
