I'd recommend German Autotech on Colby Drive in Waterloo. Their website is: http://www.germanautotech.ca.

It's a nice, pleasant and efficient owner-operator business, which is the type I prefer.
   
They seem to know what they're doing and don't mess around with shoddy parts/oil/filters, and similarly they don't upsell you on anything like these clowns.
