Advice/question
 

Guys this may get a little lengthy: my 2013 is up for return in a few months I've got the 35i m-perf and m sport along with adaptive 20"s and a bunch of other stuff.

I just found 2 50is 2016 to look at one is an m sport, 20"s, and a bunch of other stuff including bang olufsen, the other is the lux line BUT and his is a big one has DHP (dynamic handling package) instead of bang olufsen this one has rear entertainment since I got kids that's a little more practical. Here is the question standard suspension with 20" vs dhp with 19" is there a comparison? Seems like dhp is kick but awesome but aside from the paddle shifts and more aggressive look what am I not considering in m vs lux?

Lastly all new models have the comfort-sport button which makes me confused what the different options are and if/how they impact that button. Any suggestions highly appreciated along with which one to consider.

Thanks in advance

I strongly suggest you test drive them both before making a decision. The suspension is much different on the F15 then what you are used to in the E70.

Good luck.
