READ MORE TESTIMONIALS »“My car and I wobbled into the shop as I was driving to work one morning. I'd never been to computer Tune but it was the nearest to where I was. I explained my situation (it's wobbling!) to the owner who was there that morning and he said, "no problem, here's a loaner - no charge for that - get to work and we'll call you." What? A Free loaner to a person who didn't have an appointment? wow! Off I went in a very nice ford that was very clean inside and out. I got a call at work about an hour later with an estimate for my problem, along with estimates on my several other problems, including a faulty blinker and missing/broken side mirrors. I had priced out the mirrors elsewhere but the cost was tremendous and not worth it to me, but computer tune offered me a very low price - and they had both mirrors in stock! Now who would think a place called "computer Tune" would have parts, but there you go. My car was ready for at the end of the day. Again, I didn't have an appointment but they patched up all my issues - and an oil change - in the span of 8 hours. listen to me and take your car to computer tune and see Daniel the manager and mark the owner. they can help you , at a very fair price!”- Paula, Middletown CT
