Base code is S16. An interesting car to see driving around in real life and an interesting car to have sitting on my desk as well. It's one of the first cars I picked up that restarted by car collection. It bothers me a bit that the size of this model doesn't sit well in regards to scale of other MatchBox cars (it's bigger), regardless it's nice to look at. It's also my cats favourite car to play with and push around so it's already gotten some scratches.
