Because I mostly play Assetto Corsa, I naturally wanted some modern TCR content. Kunos isn't going to do it. They're overly focused on GT3, like every other sim, which I think is mostly shit. There are a few free mods, such as a few TCR cars from AssettoGarage. I suggest that you never bother with AG content, it's all shit ports from Project Cars and other games - no OC at all.
As I said, I'm left to paying for a few cars. I find a really good set of five cars but they're €15 (19+ American currency pledges), which is insanely high. Of course, I bought it because I always make good decisions at 3am. It's good content but no where near worth $19. RSS/ACFL will get you a full field of current F1 cars for half the price and better quality.
I'm just venting on a stupid purchase. Anyway, the was Alfa Romeo Giuletta is pretty good so fuck it.
