Depending on the dealership, that might be possible. I'd imagine a big ticket item like a Mach 1 going missing long enough to be repaired would be pretty damn unlikely - impossible at mine.
If it had been fixed under the table, when the Ford rep shows up someone will probably loose their job. Wouldn't be hard at all to find all the Mach
1 rims shipped to that area and where that tire came from.Wulf
