It has 27k miles on it and is loaded, but after reading all these posts and hearing from him that it was a buy-back due to a brake light that wouldn't go out (1st owner lost confidence in it after 1 year of repeated problems with that light), so I'm a little concerned. Then, when I took it for a test drive, I notice the yellow engine light was on. They told me today it has a bad EGR valve and they want to keep it for a week and make sure there are no issues with it or they won't sell it to me. They have made it a CPO so the warranty is extended to 100k miles. Seems like an overall good deal, but now I am starting to wonder.... Are a lot of people having problems with their 35d's or is it just a few that are talking here to try to figure out what is going on? I've gotten some great info on the E70 here, but I am just looking for some feedback before I make my final decision. Thanks in advance.
