secondhand toyotas are incredibly overpriced imo and the RAV4 is unibody afaik. i know they don't make that config anymore but it would've only been worth buying new.
for an import SUV at that price i'd find something body-on-frame like a 4runner or an FJ cruiser. or even a land cruiser if you don't mind the size and horrible mpg.
also, since we've owned the jeep my feeling is that v6 is sort of the worst of all worlds: you don't usually find them in the most utilitarian package and the mileage sux.
