Slow...very slow. Had my 2013 Buick LaCrosse towed there at 9:30am due to needing a new battery. The one in the vehicle was leaking acide. It took them from 9:30 - 4:30 to replace the battery. I even called twice during that time for updates and never received a return call. To top it off, when I arrived, they couldn't find my knew fob.
