<p>I am actually in the same boat, so I've been researching used car market in the US for half a year now. My advice is: the more you research, the better car you're gonna get. Portals like autos.msn.com, autos.yahoo.com, edmunds.com, carsurvey.org are good for researching used cars. For local car listings check out cars.com and autotrader.com. Also, when you choose a particular model, you can try to look for fan club webistes with a wealth of info about the model, e.g. its troublespots, solutions, etc.</p>
<p>As of what model you should choose is solely up to you, but I cannot stress it enough -- stay away from American cars. They are poorly built and were designed with absolutely no sense of style. While Japanese cars (especially older Toyotas and Hondas) have little style in them, they at least have a good reputation for reliability, which makes them a good choice. I also think that 1999 Mitsubishi Galant is decent model with not too many mechanical problems.</p>
<p>As of myself, I am a European, so each time I see a Toyota, I think of LADA (check out Wikipedia, if you don't know what it is). It is not enough for me to have a car that will go forever, but has the same feeling as LADA. That's why I am considering buying a Volvo or a SAAB. SAAB 900 (the renewed version from ~95, I think) doesn't have too many technical problems. As of Volvos, a synonim of safety, 850s are great, not so sure about S/V70 (XC). Plus, all those Swedes are easy to fix yourself with a little technical know-how and a repair manual (I think I won't mind fixing my car). Another point about Swedish cars is that they are usually built to last. I wouldn't have another look at a Mitsubishi Galant with 150,000 miles on it, but for a Volvo with all the repair documents and good maintenance, 150,000 is not bad at all! It should be good for well over 200,000 miles, and some owners pull as much as 330,000 miles from a Volvo (not to say that you should be looking for one with high mileage)!</p>
<p>When choosing a car, make sure that it's been properly maintained, check the title history, take it for a test drive, and be extremely careful when checking the automatic gearbox, if you don't want to spend $2000 -- $3000 for repairs later. Finally, take it to a mechanic to see what technical problems it has/might have.</p>
<p>Good luck!</p>
