Meh...
I usually love these types of games, but this one has some serious flaws that make it less enjoyable to play.
There were things that weren't explained in the rules, like the fact that you can collect money from multiple customers to save time. Also, the customers are WAY too impatient, even with the car wash option. I upgraded my characters speed, but he was still too slow to keep up with all the customers.
Straighten out some the issues mentioned, and I think this game would be a lot more fun.
