I downloaded the car and I honestly loved it!
The handling is great and the car is really fun to drive, plus the ffb is very good!
It is very easily damageable but the damage doesn't seem to affect performance much: I've just finished a 40 minutes race against the AI at Bathrust where I'd broken my suspension on Lap 1, but the car was totally driveable.
Only thing I noticed which bothered me a little, albeit maybe it's representative of the truth(never really followed WTCC irl, not much coverage for it here in Italy) is that the engine overheats really fast, and it is really hard to make it cool down: when driving at race pace, my engine overheated after around 4-5 laps, so I had to slow down and give up some time to the AI in front.
Anyways, thank you very much for your work, it is a great car and I'm sure I'll be spending many hours driving it!
