After being jerked around by some local mechanics, who didn't solve the problem with my diesel van, I was relieved to have found Dirk's. The mechanics there thoroughly diagnosed the vehicle, and, step by step, got it up and running in good form. Thank goodness. The office staff was knowledgeable and friendly, and the mechanics were skilled and the whole process was professsional. If you need a vehicle diagnosed, go to Dirk's. They know what they are doing.
