Sounds like you bought from motorline or the valley one. Just my guess....
I would push for a new car. You paid 65k for a new car, not a refurbished one.
But if you dont mind that, then just keep the car and enjoy it without experiencing further down time.
Good luck and let us know how it goes.
Maybe its just me but my experience with BMW hasnt been very pleasant at all. They certainly have a different feel to it now compared to 2000 when i got a 318.
