We recently took our Smart to RCTS Technologies. One wrench service was $290 and they were friendly and knowledgeable. We took it back for a engine light problem (engine sputtering on cold days). They couldn't find the problem, made a bunch of suggestions, and said they would continue to research the problem. They didn't charge us for that visit. I am much happier to bring the car to RCTS over Lonestar here in Calgary. We received poor service from Lonestar over the 5 years, and paid a lot for that poor service.
