OK - I am looking at a 2000 GS300 w our local Lexus dealer. He thinks that since it is certified it is worth more. I am not completely satified with the car as it has a lot of pits/chips in the paint on the front end that have been repaired. He wants to have the front end repainted if that is what it takes to make me happy. I am inclined to wait on another car that is in better shape. My question is if I were looking at two identical cars how much more should I be willing to pay for the Lexus certification?
