Proper car maintenance will help a vehicle live longer, just as proper muscle maintenance will help you save a car from drowning. Be a hero with today's Groupon: for $29, you get two standard oil changes at Synergy Auto Care in Spring (a $59.98 value).

Synergy Auto Care's master-tech certified mechanics sustain cars with up to 5 quarts of standard motor oil. Engines let out a gasp of relief as mechanics evict the old, sludgy inhabitants and replace them with clean, lubricating oils, which boost the car's self-esteem enough that it revs its engine and starts posing for cereal boxes. After steering their trusty steeds into Synergy's auto infirmary, drivers can relax or play with the office dog, Dolly, as they listen to their car guzzling fossil fuels in preparation for captivating performances on the road, highway, or dance floor.
