Best bang for buck that runs forever!
 I got this car as a graduate student in 2000 already with 100000 miles on. 7 years later and now at 253000 miles, it still runs like the first day I got it! I've only started to use premium maintenance parts on it 6 months ago (synthetic oil, good filters, good spark plugs which I doubt played any part in the reliability). It is still giving me up to 36 mpg hwy!!  It has no rust - tiny spots on the front due to stone chips easily fixed with a tiny scraper and a touchup paint pen.  Engine uses timing chain, superb reliability. Major maintenance in the 7 years was a starter, a clutch, a muffler, CV joint (shaft). Usual parts: batteries, brakes, fluids and oil, filters and struts.
