Michael has taken fantastic care of me and my '96 T100 pickup. I had him do the brakes that were [embarassingly] long overdue. He did such a great job for such a reasonable price that I went back and had him replace the timing belt& water pump as it was due. He noticed the cam sensor was pinched and the wires were crimped from a previous, shoddy install. He replaced that while he was in there too, I appreciated this attention to detail. Found my mechanic! Thanks Michael!

Mike went out of his way to find the problem with our car. He proformed many diagnostics and spent more time than he charged for. He is very knowledgable with his background in the automotive industry. He is good and his pricing is fare. I would highly recommend Mr. Tune Up's Auto Services.

Michael was an exceptional professional who was very communicative about my A/C issue and what it was going to take to fix it. I found him quite trustworthy and knowledgeable, and at a modest price. Additionally, he had me in and out within a 24-hour period. Granted, my issue wasn't too complex, but I was happy he was able to accommodate an easy fix so quickly. I was actually referred to him by my father-in-law, who also uses him for his truck maintenance, and my father-in-law is extremely cautious of who he uses for his own work. I would highly recommend Michael and Mr. Tune Up's place if you're in the Falcon/Peyton area.

We highly recommend this place! Michael O'Neil is exceptional in his knowledge about vehicles and pays attention to details. He is honest about what needs to be fixed right away and what can wait. He will explain what is wrong in layman's terms. If you want repairs and/or oil and filter changes done right, go see Michael. You will not be disappointed!

I highly recommend Mr. Tune Up's Auto Repair. Mike quoted me a price that was $1,000 less than my dealer. Mike goes the the extra mile, has integrity and will not sell you parts you don't need. If you're in need of an auto mechanic that you can trust, look no further, Mike's your man! Couldn't recommend him enough and he's well worth the drive!

Michael is truly the unicorn of auto mechanics. You will not find someone more honest and trustworthy to fix your vehicle. I took my Toyota venza to Michael after running over a grass catcher dropped in the road. It ended up taking out my vehicle stability control. My car was fixed and ready the next day, even and the middle of a winter storm and a full day earlier than promised. I cannot recommend Mr. Tune Up's highly enough.
