I've spent a bit of time recently alternating between using GMCreator and tweaking it, with the goal of making more of the Complete version's new content purchasable instead of scattered around as prize cars.
The C55 AMG is now available in the Special dealership at Mercedes-Benz, with the CLK Race Car moved to a second page. The C55 was an obscure special-order car with only a few dozen hand-built, so I figured it warranted special status. I've also boosted its price since this screenshot was taken - it's not the most expensive road car in the game but it's in the top 20. Back in 1999 it cost quite a lot to pay Mercedes to build a C43, ship it to AMG, and have everything under the bonnet and floor replaced.
Ruf on the other hand has received a whole extra page in its New dealership, with the four restored 964-based models all up for sale instead of unbalancing the early game prize pool. They will still show up as opponents in events though, to remind players that they're there.
Because of the above changes, the number of new early-game prize cars will be reduced, however there are a couple of new additions planned so that I can still hide a few unique rewards in there. This time around, they'll be a bit more balanced in terms of value and performance than a free 425ps Ruf!
