I've been there and tried using that coupon. It's a scam. They just want to sell you "The Dream Package" which costs $99. All you get for that coupon is 5 minutes in their waiting room and some bad coffee. I don't even think they touched my car. They should stick to making movies!
That reminds me of a billboard I saw a few years ago while driving through South Dakota. It was for a service station that apparently offered some sort of "Toe Service." I was deeply concerned.:huh:
