I should've known that a mechanic who has the $ to pay for TV commericals is making a lot of money at the expense of customers. They are slick salesmen who assume that we know nothing about our own cars, and try to sell you on everything. Do not trust them, they will rip you off. I've worked on cars for years and have known trusted mechanics for years, and it is easy to tell when they use Scare Tactics to con you into spending a ton of money. Go elsewhere to avoid being cheated. I got second opinions from another mechanic who agreed that these guys just want to take your $$$!
Cons: They are crooks!
