"I called because my check tire message illuminated on my GLK 350's dash, E.A.R. Leo fit me in first thing the next morning and did a complimentary inspection, addressed an issue with the sensors, and sent me on my way within an hour without trying to sell me any unnecessary repairs. The local MB dealer will charge at a minimum, $300 for a diagnostic reading/turn off your dash warning lights. Lucky for me there was no major issue, but I know they've gained a customer for even the most routine of maintenance. "
