I think they are pretty reliable cars (its toyota after all), but if you are looking for a completely reliable car I don't recommend you getting a turbo 4wd car. Even Though its a Toyota, there are more mechanical parts that could tend to failure (turbocharger, 4wd system), I think the GT4 its an excellent car, but the truth is that its a pretty old car, turbo, and really complex to work in. I would recommend getting yourself a 7th generation, is newer, and probably you won't spend a lot of money in maintenance and gas. Good Luck!
