have mostly avoided those. the main car thats disappointed me is the formula rookie; i would like to see crappier tires as an option (and i did some research, this is in line w/ reality, as the formula ford its based on uses both slicks and 'historical' tires). i was looking forward to racing this as i hoped it would be formula vee-like, or at least SB like, & its neither. will still prob race it a fair bit.
favorite so far is probably the caterham classic. havent tried the superlight. i like the road cars, im really surprised. i think theyve done a really good job. i just drove the P1 on nords in pC & AC back to back & pC is the one that makes me feel that a driver of my talent running no assists but ABS is not just stupid but absolutely crazy. AC, its a little less forgiving maybe, but everything feels more under control. you can interpret that however you want ofc.
GT3 seem fine, havent driven it much except to compare grip levels b/w sims early on. i REALLY like the formula A & thought the formula gulf is a helluva lot like AC's abaarth (both just very solid cars).
so far unfortunately i agree about the zakspeed & merc 190 dtm; i felt both were a step down from what S3s done with them. im actually not to familar w/ ACs 190 or the capri mod but my memory regarding the latter at least is i enjoy it more than the pCARS one. maybe pC is more realistic, again idk, but that awesome turbo lag sensation is really lacking in pC & i cranked up the boost all the way.
overall its actually growing on me so far instead of the opposite; continues to surprise me.
