maybe it's my driving style, I really don't see or experience the throttle issues. I drive almost exclusively in sport mode and I rarely use the paddles. what lag I experience is very similar to my former 2013 335, stick. there I shifted
I really like my car wish it had Android auto and blind spot warning (it would make Mrs. rounderman happier, but she likes the car overall)
I grin when i get in it. definitely try the m35, is it perfect, of course not, but a good mix of fun and practical.
enjoy the hunt
