researched area repair shops and found great reviews for this shop. dropped my cayenne off at 8am and added some additional items to take a look at. they said they'd get it all done and I could pick it up the next day. this included valve cover gaskets, spark plugs, ignition coils, control arms, tires and an alignment. got a call to correct the cost and then another call the next day to say they would be done on time. I came by at 4:30 on a friday and everything was fine. all done. great service. great communication. great price.
