March 15, 2023These guys are known for their quality and on time repairs. Professional services. Completely satisfied. I use to take my truck to the dealership. These guys are as professional as the dealership if not more but won’t break the bank.

January 28, 2021Great place and extremely accommodating staff ! They diagnose the problem and are very honest about the diagnostics. Unlike dealers like Volvo, they make you feel at ease and you actually feel a difference in your equipment before and after We are based out of montreal and prefer sending our drivers to their garage to get issues resolved (which they actually do) Very happy with their professional service, attitude and skills
