Service to our Community

We don't just operate in your community -- we are an active part of it. We try and do our part whenever and wherever we can. That's why we participate in such programs as Cell Phones for Soldiers, DARE, Internship & Co-Op Apprentice Program with Monty Tech; We contribute to the Clinton High School After Prom Safe Party Fund; We contribute to many local programs and volunteer time and resources when and where we can.  (Read more about what we do in your community here..)



Anyone can replace parts.  Good technicians and know how to diagnosis your problem.

All of our employees are ASE Certified Technicians who have 15 or more years experience in auto repairs and diagnostics.  We use all resources that are currently available including  Identifix and AllData computer systems which provide technical information on all vehicles, including Web access to manufacturers’ information databases; as well as the latest technology including computerized engine diagnostic with Snap On Solar Scanners and OBDII Scan Tools (OBD: On Board Diagnostic).

 See what our customers have to say about us here.

We want customer loyalty and will work to obtain and then maintain yours with each service or repair we do.

Our knowledgeable and friendly technicians never promise more than they can deliver and we strive to give our customers more than they expect.

See our Helpful Info & FAQ page for much more information. At Guaranty, we find that educated customers come back for routine service and repairs because they feel comfortable. We work hard to build that trust and give you that feeling.

Our technicians do NOT work on commission basis as some shops do. We also do NOT have a Service Writer or Service Advisor. (Meaning our Technicians do NOT get paid a commission for selling more). You deal directly with our technicians on a one-on-one level. Although our office staff is happy to take in your vehicle and make your appointments, ANY time you wish to speak with a technician directly, one is available.

LET US BE YOUR AUTOMOTIVE HEALTHCARE PROVIDER! ALL your automotive needs are under one roof at Guaranty!

Massachusetts Registered Repair Shop #3077

Last Update: 10/1/2010

Yes, we fix cars and trucks...

but our goal is to maintain your car, not fix it.

Preventative maintenance saves you money! Vehicle maintenance is just like brushing your teeth or going to the gym to workout. It takes time and commitment. The benefits to your vehicle are the same as to your health. A vehicle properly maintained and kept three years after your payments end could save you up to $20,000! 

Guaranty Auto wants to be your Automotive Healthcare Provider.. all your automotive needs are under one roof at Guaranty.

Every time you visit our facility, we will raise the hood and check all the vital fluids. Our service team will then make maintenance recommendations based on the condition of these fluids, the odometer reading, and the time interval since your last service.

For your convenience, we are attaching some common Automotive Service Tips and a Service Interval Schedule developed by the Car Care Council to help you keep track of regular maintenance needs too.

Clinton Collision Center

Here are just a few reasons why we consistently out-perform our competition:

Integrity is the difference between a vehicle that

     it.  We meticulously restore your vehicle's
     original factory appearance and repair your
     vehicle so it once again meets factory
     specifications.  At Clinton Collision, YOU are our
     customer, not the insurance company!  We do
     whatever it takes and negotiate on your behalf with
     your insurance company for ALL the repairs
     necessary to restore your vehicle to it's pre-accident

We want customer loyalty and work hard to
     obtain and then maintain yours.  We can't
     achieve that unless we are consistent and
     honest.  We'll work hard to build your trust. 
     Please read our
Mission Statement and Code of
for more information.  Also, check us out
     with the
Better Business Bureau and the MA
     Division of Standards.

We pledge to keep you informed at all steps of
     the repair process until we hand you your key.

Commited to quality, our technicians have the
education, experience and skills to deliver what
     we promise and are qualified to restore your 
     vehicle to it's pre-accident condition or better.
