I'm already pleased with the feel of netKar Pro, so knowing this might be an step up, I'm already preparing to spend cash, if it's not an ripoff like iRacing.
I had some interest in this in passing, with intentions to try it out when the time comes... until I saw the ass-end of the Lotus in the OP. Now I'm excited and I want it!
Apparently, every car that was in the intro video on the website is going to be in the sim. That means Lotus T125, Formula Abarth, BMW GT car (finally someone!), and many others.
