Consumer reports. Find what you need, which vehicles fit that need, and finally which one fits your budget. If you are looking at a car a few years old, CR will have enough feedback (data) about areas of concern - transmission, electrical, etc - so you can focus on cars that not only perform well and fit your needs, but ones you won't have to dump money into.
Anecdotal stories about "oh, man, I had one of those, good car" or "mine broke all the time" don't tell you anything - ANYTHING - about potential reliability or how you would like the car.
