Yeah i've never been stranded by the MS either...I do carry a spare, but never had to use it. This car has been with the MS for a few years now, been to Chicago and back to Michigan 2 times(4 hour drive each way), and to the DSM shootout and back 2 times(3-4 hour drive each way). If the MS was built properly, and it was done with care, the only issues you may have would more than likely be user related..(wiring, tuning, ect..) The MS is the shit :)
