Like athletes, vehicles cannot perform without proper juices flowing through them and without heavy endorsements from Wheaties. Help your car power through with today's Groupon: for $20, you get an oil change and multipoint inspection (up to a $39.95 value) at Marvin K. Brown Auto Center in Mission Valley.

The factory-trained technician team keeps urban ponies road-ready with a number of maintenance services. The oil change and multipoint inspection switches out each car's oil and oil filter for younger, more attractive ones. Oil plays an important role in keeping friction down in the engine and preventing the motor from seizing up or seizing the proverbial day. The treatment also includes a 27-point inspection in which technicians will check tire pressure, wiper blades, break fluid, and the car underbelly to ensure everything is working properly. Finally, a tire rotation will allow more even tread wear, thus extending the life of tires to continue screeching donuts around donut stands.

During the service, which normally takes 60–90 minutes, the car's restless owner can take advantage of the three on-site service department shuttles or use the on-site Hertz auto rental for a no-strings-attached joyride fling. Clients are also free to take a breather at the nearby movie theater or Mission Valley and Fashion Valley shopping centers.

Though the auto center's website offers the oil change and inspection for $10 off for Saab, Suzuki, or Mitsubishi cars, all Groupon customers can service cars for only $20, making this a better deal with a longer redemption period.
