So I noticed from reading on this site that 3rd gens can have rust issues. I'm currently looking at this 3rd gen and thinking of buying it but noticed from the video the dealer sent that the previous owner spray painted a lot of the under carriage...meh. Bad sign? The rest of it looks very clean. Let me know your thoughts. Am I better off finding a 4th gen? Here's the video - 02 4runner customer video(1) - YouTube
