I was unaware that Costco had the convenience of a car wash at the San Juan Capistrano Warehouse and found it to be an outstanding value and experience. Our car is valued at over $60,000, was it a risk to wash the car through this fully automated process, I think not!
I have come to trust Costco with all of my valuables and lets face it most commercial car washes are extremely abusive from the minute your car is being washed.
I would suggest once the car has completed the wash and dry process pull over to a parking space and inspect and final dry the car yourself. Our car came out beautiful!
