Reviewed by Larry Underwood from Granby, CTNovember 27, 2025

O'Neill's service department has always been very easy and pleasant to work with. Michelle has been extremely helpful making service appointments and guiding me through the maze of GM's product offerings and requirements.

Reviewed by SMCNovember 24, 2025

2018 Suburban was brought in for running rough approximately four months after a 90K tune up - dealer stated nothing wrong. Vehicle was brough to another shop that cleaned fuel injectors and replaced the recently changed spark plugs - vehicle now runs smoothly with better performance. Will not return to O'Neill's for service.

Jose kept me informed of the work that my car needed and the cost. When I picked up my car it was raining so Jose brought my car to the door so I wouldn't have to walk through the lot to get it in the rain! He provided excellent, kind customer service!
