Friendliness and organization of overall business and staff, great customer service!. The fact that your business provides a shuttle for customers. The details and explanation of tech analysis is most appreciated and convenient. To be improved: when a light bulb is detected not working, either phone me to get approval to change it or just change it (in this recent case it was a burnt out brake light of which I shouldn't have left your shop with it out, just change it I will forgive you) and when you found my block heater cord not functioning, please phone me for quick approval to find the cause and I would approve fixing it (as the weather forecast was for -29) hence it is the North and I do need the block heater and would like it fixed while in your shop without the inconvenience of another appointment and/or not being able to start my truck. Thx
