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 to Henry Clay Motors. Choose between the following options:

• For $10, you get an emissions and safety test (a $50 value).
• For $35, you get three standard oil changes (an $89.85 value).<p>

At Henry Clay Motors, a master technician certified by the National Institute for Automotive Service Excellence oversees a team of mechanics that maintains road-worn rides. The mechanics each boast at least 15 years of experience, which they use to evaluate the performance of more than 40 vehicle components during state-mandated safety and emissions inspections. A requirement for vehicle registration, the approximately 30-minute checkup encompasses the condition of wheel bearings, brakes, and fuel-system lines. Crews also determine whether the catalytic converter is belching dangerous compounds instead of its usual pledge of allegiance.

Alternatively, regular oil changes mitigate the damaging effects of searing heat and constant friction on mechanical parts, thereby extending engine life and enhancing its performance. During the one-hour sessions, technicians pour up to 5 quarts of standard oil to refresh motor cocktails. A fresh filter stays behind to maintain automotive fluids and prevent breakdowns in dark forests full of lumberjacks trying to get rides to the mall.
