DO NOT TAKE YOUR CAR HERE. I have lived in Rockville for 20 years now, I was looking for a new mechanic and I tried Hickman's 2 times, both times the owner John Hickman was very rude, has a bad temper, and most important OVERCHARGES for the smallest items. Do not take your car here, find another mechanic and dont waste your time. I found out 2 weeks later that my neighbor had been taking his car here for multiple years and had multiple issues caused by the mechanics. You will over pay, and for what, a bad attitude from the owner? Don't waste your time, find another mechanic.
