I had called 2 GM dealerships to inquire about cost for installation of a block heater in my 2016 Buick Encore (moved from Eastern Canada to Northern Alberta so figured I would need one before winter sets in). At the two dealerships I called, I got different part numbers and costs. When I called you, your guy took the time to get me the right part numbers, double checked and confirmed they would fit. Your price is also about 20 % less than the dealerships quoted. Wish I was in Red Deer so I could get the installation done at your company but will order the parts and get it done at my local dealership while still saving $100. Thanks guys!!!
