If the car has been maintained properly (oil changed every 3,000-3,500 miles, transmission fluid if Auto changed every 30,000 miles, 60,000 miles if manual, chassis lubed every couple of years) then 200,000 miles is easy. 208,300 miles on my 1988 Accord (3,400 miles on the rebuilt tranny), all engine internals are original, burns absolutely no oil, everything works fine mechanically speaking, sunroof doesn't even leak. I got the car with 168,000 miles only to find out at about 180,000 miles that the tranny fluid had never been changed. :| Then at 204,900 miles the tranny lost 4th and reverse. When buying a used car, you should change all the fluids just to be safe. When not abused, Hondas are good for 200,000-300,000 miles without major problems.
In the price and age range you are looking at, I'd say that for pure reliability, Honda and Toyota are the only two brands worth considering. If you go to cartalk.com and look up owner loyalty, (Would you buy another car of the same make, Y/N?) Honda is second only to Porsche.

EDIT:
- The only American car in the top ten is the Saturn (not counting the "American made" Honda).
We don't get to another American vehicle until the 17th-ranking Jeep.
The "Bottom Ten" -- with Kia "leading" the pack, contains a lot of low-priced Korean cars.
The Bentley is down there too (in case in was on your list of "maybes.")
