Can answer all Volvo car questions. European and Canada spec cars are different but I can try to help you.


I am a Certified Volvo Tech at in Independent Volvo Repair shop. I grew up around Volvos and decided I wanted to do it professionally. I worked at the dealer for about a year then I went to work at an Independent shop which I have been with for 10 years.
