Put deposit on a 2017 Shelby on a Monday. Financed vehicle, had check in hand, and was to make 6 hour drive to dealership on Saturday to finalize deal. We had a massive snowstorm in my area, so I contacted dealership to advise that I would not be able to make it until Monday (dealership closed on Sunday). Was told that they would not hold vehicle, regardless of deposit, and would put vehicle back up for sale. I offered to overnight the check, to no avail. Reluctantly, I made the trip to the dealership only to discover that the drivers side door of the vehicle had a fitment issue (not disclosed by dealer prior to purchase). General Manager made aware, would not personally discuss the issue, deferred to the salesman who was unwilling to resolve matter. I have been buying a new vehicle every 2 or 3 years for the past 30+ years and have dealt with many dealerships across many states - this is the first time I have ever had such a negative experience.
