I was wondering what day my smart was built. The door jam sports only the month and year. I stopped buy my smart dealer and asked the service rep if he could help. He jumped up, walked to a computer, then returned with a smile. He had the date. My car was built. February 8, 2008. He also found the date it arrived on U.S. soil. March 14, 2008. So if you want to give your smart a birthday party just check with you dealer.
