It has been rumoured that that might be because the class is still open, meaning there are still cars in the making that might be added and a pack will be offered once the class is "complete". While I don't know if that's the case I also lean towards that explanation.
Well, but as mentioned before, the Hillclimb Pack consisted of the Carlsson SLK and the RaceRoom Hillclimb track at the beginning. Later on the Bimmers were added. If it's the reason further cars should be added, we will have to wait or to buy. Nice would be a statement by s3s.
Yes, yes, yes!: Please S3S, get the full GTR3 cars/liveries into a pack (and while you're at it, all of the other un-packed content). I'd really like the cars, but I also want all the liveries and can't even determine how much that would cost if I bought everything separately. The recent change to allow a purchaser to pick the one included livery was nice, except that, as far as I can tell, there's now no way to see the prices for all the remaining liveries until after you own the car. If this situation is because more cars will be added to the GTR 3 class, then just either add those for free to customers already owning the pack or charge the reasonable difference (as with the "already owned content" type of discount). Thanks! Justin
