Well, not being an actual owner, I'm sure there are more qualified members on here that could give you some input. Anyhow, my dad picked up a 2015 RC350 F a couple of weeks ago, and I got to put about 100 miles on it myself last week.
Mostly doing mountain roads, sadly I never took it out of 'Normal' driving mode, but it handled quite nicely; had plenty of power for my tastes. The most impressive thing to me was that it handles like a sports car but the ride is like a luxury car. I also couldn't help but notice all throttle and brake inputs were gradual not jerky, a very refined automobile.
