I have been taking my car here for years and have been satisfied the majority of the time. They do an average job cleaning up your car for the "regular" washes but I would recommend you look it over before you leave. If you point out anything they missed before you leave they will fix it with no argument. The only problem is the workers where you pick up your vehicle usually do not speak English so you have to find a way to explain what you want fixed.
I hate it when you go to a carwash and the sales person is pushy about getting extra services when all you want is wash. TNT is better than Cobblestone in this area but they are still a little annoying.
I have gotten the full detail on my vehicles 2 times at TNT. I was happy with the work but I felt it was a little overpriced and I have found other full detail services that will do a better job and charge less.
I have never gotten an oil change/lube service at this business.
