I am doing some work on a 250SL for a good friend of mine and happened to look at the body plate attached to the left front inner fender. The second line of embossed numbers caught my interest: it has the first 8 digits of the VIN and then a single digit separate from the rest at the end of the line. According to the Data Card section of the Technical Manual on this web site, this single digit gives the market the car was built for - most cars here in the U.S. have a 7 - America; my 250 California coupe has a 2 - Germany; my friend's car, interestingly enough, has a 4 - NATO, Visitor, Diplomat. His data card shows the car was built to European standards, like mine. In fact, according to the data cards, our two cars left the factory 13 days apart and were shipped to the same dealer in Nuremberg.
Curious about the NATO thing. Does anyone know why NATO had a special market number? What would be different about the car from other markets? Is the "4" commonly seen on the body plate?
