Nothing ruins your day like having the service light, the transmission light, and the check engine light come on all at once after you've started up your car. Needless to say, I had to take my S40 in to the shop immediately. Mark, Nelson and the crew we're friendly, helpful, and honest. They diagnosed the problem right away, explained in detail what needed to be done, and were able to do all the repairs in the same day. Mark gave me a price break because I had a good amount of work done at once. My car is now running better than it has in years. I will be taking my car to Mark's from here on out!
