Every series in the CS system opens the cart with Formula series cars and/or tracks which of course is not what I'm looking for because there isn't even a current Formula series going on for the CS system atm. Anyhow, Rookie, mini etc. Doesn't really matter. If you click to go to the shopping cart it just loads up with Formula packs etc. Not sure what it's all about. Perhaps because I already have the content for the series that I'm racing it just defaults to Formula stuff. Anyhow FYI.
