Cars need regular oil changes to keep them running in top form, just as winning racehorses need periodic blood transfusions to keep the drive for victory coursing through their veins. Treat your chariot like a champ with today's Groupon to JB Autoworks in Holland. Choose between two options:

• For $20, you get a semi-synthetic oil change (a $39.99 value).
• For $49, you get a Weekender Special auto detailing (a $99.99 value).

The automotive jockeys at JB Autoworks pander to the cleaning and upkeep desires of traditional and exotic vehicles. Opt to rejuvenate a ride's famished pipes with a 6-quart semi-synthetic oil change from a skilled technician. After scrutinizing mileage, JB's tech team fills mechanical gills with one of two synthetic blends, conducts a safety and visual brake check, and lets customers choose between a new air filter or set of wiper blades. Upon completing the 30- to 45-minute fix-up, cars beam with a level of swagger usually reserved for their tool-belt-wearing counterparts.

Or treat rides to a Weekender Special auto detailing, during which a team of aquanauts hand washes and dries your steed's skin before vacuuming seats and trunk from the inside out. Once finished, interior dashes and seats beam with protectant, and a thorough interior window cleaning and exterior window Rain-X application will confuse high-speed nomadic insects. Set aside about two hours to ensure cars attain ample relaxation in the billows of JB's serene suds. In addition to servicing traditional autos, JB Autoworks also specializes in luxury vehicles, including Porsche, Ferrari, and Lamborghini.
