Certainly interested in this.
Bored of the GT3's so fine with it running beside it.
For the best RACING, the slower the car, the better the on track racing (as ppl race, rather than crash)
Imo, anything going over 300bhp just extends the gap between the fastest > slowest drivers
Some of the most fun (and best to watch) racing I've been in, was the Ginetta Junior + Touring Car leagues! If you go much beyond that, the cars spread out more on the track.
Something slow, and easy to drive will provide the most exciting racing!
BMW TC League gets my vote
I'd definitely be interested in this, but would have to choose either this or the GT3 league as I don't have the time to do more than one league at a time, as others have mentioned and a season of weekend racing is also a no-go for me.
