    Excellent service at a very reasonable price . They will do exactly what you want, and would suggest anything needed for another time.They suggest points to address and aren’t out to make a quick buck. 100% will be back.

    They do the regular service on my Chevy Express 3500 van and I've had no issues even though we tow a 7,000 lbs trailer regularly and this was a former rental van (you know how gently they are treated ;). Recently, at 210,000 KM's, they had to replace my transmission lines and trans cooler since it was leaking - good price and always friendly service. I'll be back at 300,000.
