Moralia, did you buy it at a BMW dealership? If you did, you should have gotten it I believe. A friend of mine bought a used MINI from the dealership and got the welcome package. Not sure if you bought it from say Carmax (which is where I almost bought a used MINI).
It was from a non-BMW dealership. I can't complain, though...even needing a new clutch, I paid a VERY reasonable price. I take it to the local Mini dealership for service, though, so when I eventually go to get a new or 'new' one, I'll probably go there. Their customer service is really excellent.
Also, they give me a pen each time.
