I am not a mechanic, but I take time to research what the needs of my vehicle are. I will look up manufacturer technical bulletins and also read the car enthusiast forums to get an idea of what the recommended maintenance is, as well as any special needs or fluids. I took my fiance's 07 Mazda 3 in for a much needed transmission service. The gentlemen in the lube bay knew that the transmission takes a special Mazda only fluid and even though they didn't have it in stock, had it delivered from the dealer within 20 minutes. They were quick yet thorough and had me back on the road in a little over an hour- impressive considering the 20 minute wait for fluid. A lot of peace of mind that these professionals take the time to know each car and service them properly.
