I have been going here for years- They are experts and some of the most honest people in the business. Being in Maryland, I try and save myself the drive every couple of years and find a local … More shop, but just get disappointed. So far, United Automotive has fixed 3 vehicles (1989 GMC Truck, 2009 Toyota Prius, AND 2008 Toyota Sienna) when the dealership shops said there was no hope or the price to fix was above the cost of a new car… Each time United came in with a super fair price, and the repairs never took longer than a couple of days (even with weekends) Worth the drive to have the experts who know how to do the work AND are fair with pricing to get you back on the road quickly and safely.
