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 $17, you get an oil change at Master Tech Transmission - A NAPA Auto Care Center in Walterboro (a $35 value).

Plying their auto-mending trade as members of a NAPA AutoCare Center, Master Tech Transmission's ASE-certified technicians operate on vehicles of all makes and models with genuine NAPA parts. Mechanics hoist rides up on service lifts, convincing engines to spit out used motor oil filled with part-harming particulates, metal shavings, and diet cola siphoned from the garage refrigerator. After extracting soiled oil, technicians replenish engine reservoirs with up to 5 quarts of conventional lube. While waiting the 30–60 minutes for the oil change to wrap up, patrons can kill time in the waiting area plotting their next country cruise or practicing thumb-wrestling techniques on their non-dominant hand.
