Slow motion adds dramatic effect to a scene, which explains why so many action heroes exit car washes completely soaked from trying to roll up their windows. Prepare for a climactic car cleansing with today’s Groupon: for $75, you get a full auto-detailing package at Crash Course, LLC (a $150 value) in Owasso. Larger vehicles will incur an extra fee of $25.

Crash Course, LLC's carriage-cleansing team unleashes automotive shine from within a fully equipped, 6,000-square-foot repair-and-detailing facility. Exterior detailing brushes away freeloading grime, insects and window-clinging entomologists before a hand wax sends bright lights careening off auto bodies. Scrubbed engines purr, and shimmering wheels and tires restore dirt to the ground from whence it came. Wiped windows clearly display the effects of an interior detailing that involves vacuuming the floors, cleaning and conditioning leather seats, and shampooing upholstery as well as the hair of any children hiding in the car.
