Option parts are still yet to make it to the UK... but latest I have heard is that a Yokomo delivery is due in the start of next week. Not sure about Sweden though!
The standard car with the ch'ship pack added is perfectly fine though, as stated before most of the new parts are just anodised pieces... in Japan the only options they are running with are the aluminium steering pieces BM200L and BM202R as shown on the linked list:
http://www.teamyokomo.com/ click on japanese site, go to the news update box, scroll down to the entry made on 2/27 with the words "BMAX4" in and there is a complete list of part numbers for the new ali pieces. (tried linking straight to it, and it didn't work so just follow this route instead)
Won't be long now hopefully.
