DO NOT buy into the people coming around to the door to sell a package of "free" auto care. The sales people that come to the door are extremely nice, but Tigard Exhaust is extremely rude, all of the services end up costing money--they are not "free". They sold many packages, but when you go to make appointment, you have to wait weeks before you can get in just for a little oil change. If they could not handle oil changes, then why did they take my money in advance? Because they are connning people into buying their service poor service before they have lifted a finger. And why are they so rude about it? The owner, Dave was yelling at me beacuse one of his employees had tried to get me in sooner. He is not capable of running a business. I definitely WOULD NOT leave my car there.
