Like an Olympic sprinter with his head stuck in a stairway banister, vehicle engines desperately need lubrication if they're going to run properly. Oil up with today’s Groupon: for $15, you get an oil change, tire rotation, car wash, and multipoint inspection at Toyota of Dallas (a $68.99 total value).
Toyota of Dallas's staff of mechanics pampers all manner of horseless carriages with an array of cosmetic and functional tune-ups. The 30–45-minute internal overhaul begins with an oil change (a $29 value) that swaps out up to five quarts of the auto's weary lifeblood, replacing it with clean drive-shaft serum (or synthetic oil for an additional fee), and replaces bedraggled oil filters with spunky, fresh-faced ones. Tires test their vigor with a rotation (a $30 value) and vehicles slough off dirt overcoats with the help of a thorough wash (a $9.99 value). Finally, attentive technicians pore over the combustion chariot from bow to stern in a multipoint inspection that checks fluid levels, tests brake lights, and repairs tears in the mainsail.
