Car troubles and speed bumps both come out of nowhere and slow you down, but only one can be fixed with a hijacked steamroller. Take a more well-rounded approach to car care with today's Groupon: for $25, you get $50 worth of auto-maintenance services at Colony Tire. This Groupon is valid at 27 locations.

Armed with computerized diagnostic equipment and years of auto-mending experience, Colony Tire's team of technicians keeps cars and trucks rumbling smoothly with oil changes and other manufacturer suggested maintenance services. Drivers can prep their mechanical chariots for morning commutes or evening stunt-driving lessons with a routine oil change, during which mechanics infuse engines with a fresh batch of conventional ($29.95), MaxLife synthetic-blend ($44.95), or SynPower full-synthetic oil ($69.95). Technicians make sure cars' rubbery feet can still trip the light fantastic during computerized wheel alignments ($69.95), which reduce uneven tire wear, increase gas mileage, and improve handling. Customers may also use today’s Groupon toward a transmission and coolant flush ($129.95), which can keep engines from overheating and setting parking tickets aflame.
