I'm always happy with my car when they are done but you better have patience! I've been here 25 minutes and they are just now getting to the interior! Oh and practice smiling and saying "No Thank You!" 10 times before you get here so it rolls off your tongue during the up-sell.
That being said I'm always happy with their work on my car. They do a great job, I always have a super clean car and they will go back fix anything you aren't happy with. Just know it will take 45 minutes - 1.5 hours on the weekend to get your car clean.
