“Good communication. Worked well with the rental company. Worked well with the insurance company. Fast. Quality work. What else could you want? Exceeded expectations. Highly recommended. ” – Stephen S.

“Nashoba Auto Body is Awesome. They did a few small jobs for me. Great job, and they even washed and cleaned/vacuumed the interior! Love those guys. Highly recommend.” – Jeff G.

“Hands down best in the area. I’ve had to take several vehicles there for body work from just bumper scratches, to quarter panel repair to major accident repair/body work. They’re meticulous in what they do and very reasonable. Very professional. Can’t recommend them enough!” – Kathryn L
