Mechanics souped up the earliest horseless carriages by filling them with premium oats and lovingly grooming their spoilers. Spur your steed toward the horizon with today's Groupon at Sullivan Brothers Service Center. This Groupon is valid at two locations in Kingston. Choose between the following options:

• For $39, you get three standard oil changes and tire rotations (a $149.35 value).
For $79, you get three synthetic oil changes and tire rotations (a $239.35 value).

Sullivan Brothers Service Center's three locations staff factory-trained technicians who bolster cars of all types with standard and synthetic oils. During each 45-minute service, the deft technicians drain spent fluids and replace them with conventional lubricants or high-performance synthetics, which urge the engine to perform better by crafting study cards of the owner's manual. The able technicians then eavesdrop on the car's components and assess their performance during a vehicle inspection, and conclude the service by shuffling the tire positions in order to equalize tread wear, prolong tire life, and give wheel wells some much-needed alone time. Customers who opt to leave their car for further service may hitch a ride on Sullivan Brothers' complimentary shuttle, which runs to the Kingston MBTA Commuter Rail System.

Though Sullivan Brothers Service Center sometimes features online discounts, today's Groupon is still the best deal available.
