how well does 2006 m5 hold up?
If I were to buy a 11 year old M5 I would want a complete service and repair history and then I would have a top notch BMW specialist check out the car and the paperwork.
Don't My e60 caught fire for no reason, BMW does not care. They will not even return a phone call. I have been driving BMWS for the past 15 years NEVER AGAIN
