Grumpy's Automotive is an all-purpose general auto repair shop. Grumpy's works on foreign and domestic automobiles only—no motorcycles or trucks, and no race cars. Additionally, while Grumpy's does most repair work, it is unable to install/reinstall air bags. Technically located on Canoga Avenue, Grumpy's Automotive is physically located on Mayal Street, which intersects at Canoga. Ample signage on the corner of Canoga and Mayal makes it easy to locate this business. It shares space with Grumpy's Smog Center, a testing-only emissions center in the adjacent unit run by the same owner.
