Mission Gorge Car Wash in Grantville, San Diego, operates as part of the Happy Cow Car Wash chain at 6322 Mission Gorge Road, running both self-service spray bays and automated drive-through tunnels around the clock, every day of the year. The facility includes four self-service wash bays equipped with high-pressure wands, foam brushes, and warm-air blowers, plus two automated drive-through lanes offering touch and touchless wash options. Windshield chip repairs or rock-damage cracks discovered during a self-service wash session are handled down the same Mission Gorge corridor at Liberty Auto Glass, which runs mobile glass replacements in the 92120 ZIP. Happy Cow's self-service bays dispense clear-coat protectant, RainX-branded water-repellent rinse, tri-color foam polish, and a spot-free final rinse — products activated by inserting cash or swiping a card at the bay console. The automated tunnels process vehicles at two price tiers, with the higher package adding underbody flush, wheel blast, and a hot-wax sealant pass. Each wash includes a complimentary vacuum token redeemable at the turbo-vacuum island adjacent to the exit lane. Mission Gorge Road through Grantville connects Mission Trails Regional Park to the Interstate 8 interchange, and the car wash's 24-hour access makes it a stop for rideshare drivers, early commuters, and hikers heading north toward Cowles Mountain before sunrise. New and pre-owned vehicle inventory at Norm Reeves Toyota San Diego two blocks south sends dealer-prepped vehicles through the automated tunnel for a final rinse before lot placement. The Happy Cow network operates six locations across San Diego County, and the Mission Gorge site is the only one in the Grantville corridor, drawing customers from Allied Gardens, San Carlos, and Del Cerro.
