I've been to the one in Carson an unfortunate amount of times because that's where my parents go (because it's close, ugh). I hate it. I haven't been there for well over a year so I can't remember everything they've done but I do remember having to go back to rebalance the wheels more than once and my parents coming home with their tires mounted backwards.
You won't find me going there unless it's an emergency and then I will stand there and watch them work on my car.
