Buying a new car for about 5k

I would say subaru makes one of the most reliable, but they have a known issue with headgaskets on certain years. The techs in the Subaru shop at the dealership I work at are replacing them constantly, not really that hard of a job however the parts are kinda pricey. Saab did make a good vehicle, but your gonna be looking at a rather old one for the price range your looking in.
