In that budget you really can't narrow it down to a specific car. The newest/best maintained honda/toyota would be ideal...
How's this one? <crazy link removed>
Does that price look too low for that car?
I'm not an expert, but I believe that body style accord with the V6 are very very well known for auto tranny problems.
civic or corolla. the camry or accord will be older and therefore probably more inclined to break sooner.
you can say what you want about their reputation for quality being BS, but for the price range i would be willing to bet large amounts that a mitsu or subaru would be not quite so reliable. perhaps a sentra or altima would save you a little cash over the honda/toyota, but it seems like they're not much different pricewise.
