My 2015 m235xi with 45k miles, does awesome at the track. Just came back from Palmer Motorsports in MA. Great challenging tracing with massive elevations. I get some extra traction in spots where front/rear wheel only drive cars just don't. Paddle shifting in Sport+ w/ Manual mode. It's the closest you can get to a full manual without the extra work
I just need some longer fingers or longer paddles, i moved my hands down to 9/3 to use them. I'm usually up much higher at 10/2.
