I had my car in twice last week. The first time I had two tires with slow leaks due to the age of the aluminum rims and the fact they corrode over time where the tire seats on the rims. This is not the first time this has happened and Mark and his staff took care of the problem once again in one day. The following day I hit a major pot hole and it appeared that several tires again had slow leaks. Mark took the car in on short notice, aired all the tires, monitored them overnight and as it turned out they were fine and did not charge me for the second visit. Thank you!!!!!!
