I'm giving them an additional star here because they did take the time to get to my car after calling late on a Sunday afternoon. I arrived at 3:00 or so and they finally pulled my car back to take a look at a nail/bolt that had punctured my tire to begin plugging the tire.
I received a call stating that the hole was too big to plug and I needed a new tire to the tune of approximately $375.00, which is an accurate price for that tire. I had already read some of the other reviews here and felt like something wasn't right given that I had seen the damage to the tire and didn't think it was that bad.
I proceeded to ask them to charge me whatever for just looking at it (which they actually waived) and park it out front because I would take it to my local shop closer to my home (Woodies on North Tryon).
After parking it at Woodies, I received a call saying the car was ready and the plug was fine for a grand total of $25.
My advice, steer clear of this place if you can because they obviously love to up sell you on scope of work you don't need!
