Been looking at w202s, and owning one myself i have discovered this

re 2000 cars have leather embossed MB stars in the steering wheel. Post 2000 have metal stars. In cars where the airbag deployed after 2000, the steering wheel irbag is replaced and has a metal MB star which comes standard on all 2000 and after Mercedes w202s. I had a bad wreck with the 202 in 2001 and it had the leather embossed star, but was replaced with metal. So, am i correct to assume that all w202s built before 2000 with a metal star on the drivers airbag has been in a front collision? Does anyone know if this would also apply to any other model? Is it a discreat way of letting people know, or simply an eningeering change and the leather embossed airbags weren't avaiable from MB USA parts?
