5-star Review by Rebecca Goberman

"M and M Auto is friendly, professional and thorough. We have been going to them for years for everything from routine maintenance to repairs after an accident.  They don't do major body work but do all other services. It is easy to get appointments within a reasonable time frame.  Digitally sent, detailed receipts and estimates make it easy to keep track of your car's maintenance history."

"My family has been going to M & M Tire & Auto for 15 years! Jason has always been very professional and courteous. Bill the owner is a good judge of character and it shows in his employees. I’d highly recommend this shop for any service needs. They’ve done it all for me. Lift kit on my Jeep, transmission in my Jetta! They fix everything!"
