| Any 7 series is expensive, no matter what. Just because it is a 7, you are going to pay more than a 5 or 3. Add in all the electronics and you are going to fix something. A coworker of mine had a 2001 740il w/ the M package and he told me that every time he went in for service it was at least $1200. Might be worth it. You should definitely get some sort of extended warranty. |
