I am hoping more of us owners will jump in to convince you not to worry. I do understand how you feel, but the majority of us have not had a problem at all. Lots of owners, I am sure, have piled mileage w/o an incident.

If you find an out clause (I think there is a period of time when you can reneg?), you will probably lose the down payment (if you paid one). I do hope you reconsider.

Good luck on your decision. I know I don't regret buying mine...regardless of no spare and no run flats.
