I had my Chrysler 300C 90,000 mile tune up done by Rick and his crew. Rick did a thorough examination of the car and gave me a very accurate estimate. Additionally, I had purchased a cold-air intake performance filter system for added fuel efficiency and horsepower and never got around to installing it, and his crew put that in as well for me and included it in the cost. My car has never run so well, like a top; with lots of power and I get chirps out of 1st gear; so much better than the dealer's work and BS. I have a HEMI and those require specialized skills to run right. He told me my brakes were great and was honest about that, so no work was necessary there.As a result of this great work, I brought my 2002 Excursion in for brakes work and they did a great job on that as well, so I feel much safer now, I'm in the mountains with that frequently. I am pleased to refer Rick Guardino and Dorso's Auto to anyone for first class auto repair and maintenance work by a locally owned small business. He also arranged for a free rental car for my convenience which was a nice bonus, so I had a car to get around for a couple of days.
