Pistons and shafts overheat and seize up unless protected by a slick, shiny coating of oil, just like classical Greco-Roman wrestlers. Keep your engine parts from throttling each other with today's Groupon: for $16, you get a standard oil change and 27-point inspection at Auto Tech Specialists (a $32 value), located on King Avenue West.

The ASE-certified technicians at AAA-approved Auto Tech Specialists keep pistons prancing and crankshafts cheering as they quench thirsty motors with efficient oil-change services and authentic acronyms. Filthy filters are swapped out and dirty oil expelled, replaced with up to five quarts of new fluid. Next, Auto Tech performs a complimentary 27-point inspection, checking tires, lights, and various car systems to make sure wheeled warriors are in tip-top shape for traversing pavements and scaling the walls of sticky buildings. While waiting for vehicles to be checked and changed, customers can lounge in the lobby area, furnished with toys to entertain parents and constitutional law manuals to calm boisterous children.
