Your car relies on you to maintain it regularly and not to gun it across any rivers, even if there are free Thickburgers on the opposite bank. Keep your vehicular promises with today's Groupon: for $40, you get a smog check (a $69.75 value) and a DMV certificate upon passing (an $8.25 value) at The Smog Man Test Only Center (up to a $78 total value).

Owner Philip Wells opened The Smog Man Test Only Center to help take the pain out of auto-emissions testing and provide passing grades to in-shape exhaust systems. The shop's friendly team eases the stress of chariot maintenance by completing the tests in fewer than 20 minutes, and charging a flat rate for all vehicles, including regular-size cars, SUVs, motor homes, and motor jacuzzis. A DMV requirement for all autos that must be performed biennially, standard gas and diesel smog checks run even smoother when clients follow The Smog Man’s four pro tips before visiting the shop, such as warming up the vehicle for at least 10 minutes.
