When I purchased my 66 230SL I got a service booklet that had a data card from a 1966 250S (the service booklet is also for the 250S). The VIN is 108012 12 011988. There may be someone out there who still has this car. No name on the booklet but it looks like the first service was in Bayonne France (maybe just before it got put on a boat) after which it was serviced at AutoBahn Motors in Trenton NJ. Last service was March 22, 1968 with 26,638 miles.
