Like teenagers, cars require regular attention to prevent them from locking you out, smoking, and running off with older, more dangerous peers. Prevent automotive rebellion with today's Groupon to Precision Tune Auto Care, valid at one of 15 locations. Choose between the following options:

• For $36, you get four oil changes including oil-filter replacement and maintenance inspection (up to an $80 value).
For $49, you get four oil changes including oil-filter replacement, maintenance inspection, and two full tire rotations (up to a $120 value).

For more than 30 years, Precision has helped vehicles of all sorts to run smoothly with an array of maintenance and auto-repair services. Professionally trained mechanics keep engine appetites whetted with a series of four oil changes, funneling in up to five quarts of clean lubricant and installing a new filter per change. Add a pair of tire rotations to ensure even wear among pavement-bound appendages and to reduce rubbery grumblings about never getting to ride on the front wheels. Each service ends with a complete vehicle-maintenance inspection that examines the efficiency and copasetic functioning of safety and performance equipment, ensuring that cars can stop on a dime and resist the urge to honk at flirtatious construction horses.

Though Precision Tune Auto Care sometimes features discounted prices for individual services online, this Groupon still offers the best deal available.
