My experience with Smart Service has been fantastic. Great info on the web site and prompt and courteous follow-up questions to make sure I got exactly the right stuff. Sadly, I installed my gaskets backwards (make sure the Six Star logo is facing the heads not the block!) and get to do this job again. Smart Service went over and above diagnosing MY screw-up and rushing out the new parts so I can get this done and get back on the road. They sell the right stuff at a fair price and they treat you how you want to be treated. I just wish they were closer to North Carolina!
