The Crosstimbers location for this national chain is always jam-packed on weekends, but the employees move dirty trucks, vans and sedans through at lightning speed while ensuring each vehicle is back to that new-car-smell level of cleanliness. While a fleet of attendants vacuums your car, you can wait inside, prowling through a phenomenal selection of greeting cards, costume jewelry, scented candles and knickknacks. Be sure to munch on free popcorn and shoot water at your vehicle as it rolls through the automated wash.
