Like children, cars require consistent maintenance, unconditional affection, and registration to prove legality and prevent unwanted towings. Treat your wheeled children well with today’s Groupon: for $29, you get an oil change, tire rotation, comprehensive inspection, and a car wash at D&R Autoworks in Highland Park (a $129.95 value).

D&R Autoworks keeps busy buggies gently purring with its car-pleasing combination of thorough expertise and outstanding preventative service. Cover every nook and cranny of your cantankerous carriage with a full-service auto overhaul, which keeps engines combusting and hulls gleaming like a treasure chest of radioactive talismans.

An oil change retires spent, lagging engine blood for fresh, viscous talent, and a tire rotation relieves sore auto hooves by switching them around, keeping treads deep for smoother driving and alleviating dangerous cases of tire boredom. With the complete vehicle inspection, quad-wheelers receive a thorough checkup to ensure all parts are free of performance-hindering aches and communicable diseases. After autos have been internally rejuvenated, D&R soaps and scrubs away road debris with a shine-inducing hand wash.

Because service is so lovingly assiduous, appointments may take up to four hours. As an act of overwhelming convenience, D&R provides loaner vehicles, shuttles, and vehicle pickup and drop-off services for customers who’d rather wait for their cars in the comfort of their poltergeist-infested homes.
