This is what I did... about 2.5 months ago.
Fist go to
http://www.carcomplaints.com/ and research each year and read up on the problems. It seems that there are alot of problems in 2007, I would stay away from 07s.
I went second hand, searched Craigslist, cars.com, autotrader on weekly basis, only searched owners that were selling their cars, I stayed away from Dealers. I had a bunch of cars but I was looking for good value and.... The car that I was looking for needed to have Fog Lights, Manual Tranny and a sunroof. I saw that someone was selling a Camry 08 SE with 35Kmiles for $13K, the car came with an extended gaurantee up to 75Kmils. The car was accedented... the owner told me that someone hit him in the behind, no air bags were deployed, less then a G of damage and the rear bumper was replaced.
OK... so I purchased it. FYI... I took my car to a dealership for an oil change and they informed me that my tranny was leaking oil, it was covered under the gaurantee, they needed to change a gasket, part was like 20 but I think it took about four hours of labor to complete. Basically, if you have no gaurantee make sure you check it out at a mechanic, I took a chance.
Sold my old car 2000 Celica GT on Craigslist for 950, it had 218Kmiles.
Good Luck
