Like violins, cars announce their need for a tune-up by squeaking shrilly and leaking oil every time you play Mahler. Keep your ride purring pleasantly with today's Groupon: for $14, you get an oil change, tire rotation, and vehicle inspection (a $49 value). Choose from the following locations: Auto Repair Technology in Brook Park, Royal Car Care in Brunswick, and Automotive Specialty Services in Avon.

The ASE-certified mechanics at Auto Repair Technology, Royal Car Care, and Automotive Specialty Services—with at least one Master technician on-site at all times—work to keep cars in peak physical condition. A few quarts of fresh engine oil ensures pistons continue pumping in lubricated harmony, relieved of the dirty sludge that was threatening to create internal friction and attracting mechanical-engineering students. After garnishing the oil change with a new filter, the mechanics lube up the chassis and rotate the tires to maintain even tread wear, then comb through the car point by point and inspect brakes, airbags, and ejector seats to ensure each part lives up to rigorous safety standards. Loaner cars are available for customers who feel the urge to drive while their vehicles are being serviced.
