You can go to Danny's or Full Circle and pay less for an external wash. But who wants to get out of their car, potentially wait 15 minutes (or longer), and get back into your car?
Imagine you pull up to an In-N-Out Burger drive-thru, place your order, then park your car, walk into the dining area, wait for your food, and then walk back to your car and drive off. Huh? That's every other car wash. Full Circle almost has it right but there aren't employees to dry off your car at the end of the tunnel.
Despite not having interior cleaning options, I chose to purchase a 6-month VIP unlimited wash pass. Even if there are 2 cars in front of me, I'm done in less than 8 minutes and I don't have to get out of my car.
