Me too, but I'm at 97% complete with my third attempt, and with all golds for the third time too.
When I finish, I'm going to keep a copy for safe keeping, and then start over again. Since GT4 is delayed until Spring 2004, I just might shoot for four times.
BTW, I'm keeping the 100% complete, all golds saved game just in case there is a special shared game feature for GT4 from GT3, like there was for GT2 from GT.
