Saved my life on the 401! Had a major air leak and RJ Automotive arrived within 45 minutes. Professional, fast, and very fair pricing for an emergency call. Highly recommend.

Excellent tire service. They came out to the yard at 3 AM to replace a blown trailer tire so I could make my delivery on time. Best mobile mechanic in the area.

Found a complex electrical issue that two other shops missed. These guys know heavy-duty trucks inside and out. Very impressed with the shop in Paris.
