I did it. But your mileage (and answers you recieve here) may vary. Certified Pre-Owned 2000 323ia im my case. It's going into the dealer for some molding glue issues (which I plan to make a post about). Since this is apparently normal, I am GLAD I have warranty to 100,000 miles. I'm at 61,000 right now. It's nice to be able to pull in, say "fix this" and have the dealership say "absolutely." You may save some money not doing it, but I know nothing about german cars, and peace of mind was worth it to me.
