This may seem funny but I joined the Euro race last night and realised I've never properly raced GT3. I think I confused it with GT2 and was expecting to be able to pick the Ferrari 458 GT2. Seems to be a good series and, despite wobbling around at the back of the pack, the cars seem to be fairly well balanced.

Has anyone driven many of the  GT3 cars enough to give a bit of perspective on which ones to choose based on their driving characteristics?

Assetto Corsa has probably the best GT3 BOP of all sims, so excluding old GT3s (old Audi, McLaren, Mercedes, maybe BMW) all cars are well balanced. Generally from what I noticed from my other GT3 league 2 best cars are 650s and Huracan, where 650s is slightly better on handling tracks, and Huracan is slightly better on power tracks. But it's all up to you which car you'll choose, because you can setup every car to your style.
Personally I race with Lambo because it handles neutral, and I find out how to setup this car properly - but it's my subjective opinion
Cheers and have a nice season
