I had one! The thing I like best about it, besides the way it looked and work, was the way the wax smelled. It was in a little tin and it just had a memorable scent linking it to the toy. Remco really came out with some great toys. I knew kids who had the big ships and they seemed even more amazing than the Car Wash.
Quick question here - was this the business Mr. Kelly was in before he opened his jazz club/night club in Chicago? (You see, there was a famous jazz club in Chicago named "Mr. Kelly's", and I was just wondering if . . . aw never mind.)
