115 Chestnut St., Clinton, MA, since 1979
One shop, one address, since 1979.
Guaranty Auto Sales & Service is a family-owned business that has been serving the Clinton, MA community since 1979. The shop prides itself on quality, integrity and customer satisfaction, and its team of certified professionals handles auto repair and body work so a vehicle is always road-ready.
What Guaranty Auto runs at 115 Chestnut Street is one shop covering three sides of the trade: mechanical repair and maintenance with computerized diagnostics, a full collision and body center with a continental frame machine and a MIG welder, and towing with its own flatbeds. Two of those trucks also carry the trade names Clinton Collision Center and Clinton Car Care in their lettering, painted on next to the Guaranty Auto badge.
Free same-day estimates and free Wi-Fi while you wait are the same on every visit, whether the job is a lube and oil change or a full collision repair. See what the shop covers, or send a service request and someone will call back the same business day.
