I usually get the $ 10 wash, and the results are better than going thru the gas station washes. You pay a guys and as you pull into the tunnel, they will spray off(quickly) some of the car by hand. Then you put it in neutral and get pulled thru. Wash rinse dry. The only bad thing I have had there was the last time I used their vacuums. Mine had no suction, and I looked behind me to the other vacuum to see that person frustrated with the same issue. It was pretty worthless, and I had to go somewhere else.
