Took my 10 year old car in for routine maintenance. I use Miller Auto Center because my brother went to high school with one of the Miller boys. I get a warm fuzzy feeling whenever I think of the 1960's. So even if they screw up my car, at least I got a warm fuzzy feeling. I think the odds are that a GM dealership knows how to maintain a GM car better than the average corner repair shop. Playing the odds, I hope to get a well maintained car. I really like having a 10 year old car that LOOKS and RUNS like a new car. I believe they maintained my car the way I asked. I appreciate it.
