Thank you for a lot of interesting series  

Just a question about the GT3 series: Why only the BMW Z4, the McLaren MP412C and the Mercedes SLS ? Why not the other GT3 cars? (ks_lamborghini_huracan_gt3, ks_mclaren_650_gt3, ks_mercedes_amg_gt3, ks_nissan_gtr_gt3, ks_audi_r8_lms, ks_glickenhaus_scg003, ks_ferrari_488_gt3, ks_porsche_911_gt3_r_2016, ks_audi_r8_lms_2016)

Perhaps because these cars were used less during normal GT3 series. 
McLaren MP412C and Mercedes SLS were especially rare, since their same brand counterparts were superior. 
In my opinion the usual GT3 series became a little stale, so this is a welcome change.

I like your thinking
but from what i can see all cars that Lars mentioned is DLC, while 3 cars that choosen is included in basic version of assetto corsa.

i dont know if you dont have dlc you can join or not, so i might be wrong.
i assume the reason is "so everyone could join without having the DLC"
it's kind contradictive tho, because on the track side there is DLC track included (Barcelona).
