SSR5 is a nice fit for these cars IMO, but I just feel we should have at least 1 street circuit, Rome could also work, but you're looking at 50 second laptimes there.
I'm not claustraphobic though.
For cars, I could try and spec in some Pescarolos, the BMW and maybe the R10(can't see that car working at all tbh...) Or I could make it so its just Peugeot, Audi and Toyota, which would be probably a bit more realistic while still offering a good variety of choice.
If it was really wanted, Cape Ring can be put in, but its just that stupid jump and loop in these cars which makes me not wanna do it.
