Extended warranty question. I have an 04 E46 M3,with expiring warranty and service agreements. Car has only 28,000 miles, in serv. date was Feb. 2005. I have meticuously cared for the car and my 50 something wife drove the car for 2 yrs. and has been a weekend car since we purchase a 335I for her to drive, (smoother ride for her osteoperosis, problem). The warranty is running out next month. I would like to keep the car, but have heard of very expensive repairs on M cars after warranty. I drive spirited but no racing or burn outs, etc. Do I keep the car and buy extended warranty, buy no warranty or sell out. thanks, M3 1947
