The queue stretches for half a block around the tent pitched on the side of the road. What could be inside, drivers must wonder, to inspire such a line? Grossly discounted fireworks? Eye-popping circus sideshow freaks? Free cake?! Nope. This is Supershine Car Wash, and it's well worth the wait. Underneath the tent, the service is quick and decently priced and thoroughly delivers a wash tailored to fit the needs of your vehicle. Whether you've gone off-roading, camping at a music festival, had bad luck with birds and bugs, or just pathologically avoided hosing down your car, they'll take care of you within half an hour. A basic cleaning starts at $19.95, while a $25.95 superwash comes with an exterior showroom-shine coating and interior leather protection. Take your car there Tuesday or Wednesday and get the express wax for a discounted $34.95. They'll even throw in some complimentary Wonder Wafers air fresheners, which you can whiff before choosing, so you can drive off with your car smelling like new leather, jasmine, orange slice, or any other of the 16 available scents. Who needs free cake?
