Like humans, cars enjoy vacations that are safe, hassle free, and devoid of prank phone calls from abrasive morning DJs. Ensure a relaxing trip for both you and your auto with today's Groupon: for $4, you get one day of airport self parking from Diamond Airport Parking (an $8.25 value), redeemable at the Redwood Lot A or the North Temple Lot B near Salt Lake City International Airport.

Boasting an 88-year history nearly as old as the automobile itself, Diamond Airport Parking shelters cars in comfort while owners fly to distant destinations. Each of the company's two Salt Like City International Airport lots accept autos 24/7 to accommodate any jet-setting schedule. Vehicle pilots can enjoy free amenities—from bottled water to the day's newspaper—and treat their conveyances to a complimentary car wash. Baggage assistance and a shuttle to the airport, a mere five minutes away, ease travelers' burdens and eliminate the need to hire a convoy of camels. Electric and hybrid auto owners can feed their rides at the West North Temple lot, which boasts 50 charging stations for voltage-fueled steeds.

Though Diamond Airport Parking sometimes features a discounted price online, this Groupon still offers the best deal available.
