Chris, I found a Franklin Mint die cast on e bay, it is a MB 450SL, it is an earlier car becuase it has the small bumbers, it is an american model because it has americean headlights. Comes with minature golf clubs, tennis racket and balls and gym bag, it is not cheap but it is a beautiful model, blue with saddle tan like interior. This may be hard to find becuase it was a special addition but well worth the search to find one. I have a 57 560 that is midnight blue so was overjoyed to find this blue one. Hope you have good luck.
