I too bought the state inspection discount voucher through Charlotte Observer Deals. It only cost me $15 and I was in and out in 15 minutes flat. I actually had to cancel my first appointment due to illness and they were able to reschedule me the next day no problems. No up-selling or gimmicks once I arrived. Friendly staff, super-clean waiting room (and restroom) with gratis snacks and coffee too. I also noticed they had wifi. I'll keep this place in mind next time I need repairs on my car.
