Tokens only. Machine does not beep when you have less than a minute. Then when trying to add tokens most will not take so you waste ten seconds just trying to get the machine to take your token. Soap is thick and will not rinse off. I spent $5 and the time stopped and I still had a full side of a car to rinse, and I was hauling. NEVER HAVE I BEEN TO SUCH A HORRIBLE CAR WASH. I WILL NEVER RETURN AN SUGGEST YOU AVOID LIKE THE PLAGUE.
