I can't believe bmw 4 series sport and m sport suspensions are only available in the rear wheel drive models and not all wheel drive! Why is the options so limited for the x drive or all wheel drive 4 series models? No 6 speed manual in the all wheel drive...only in rear wheel drive!!! Its Unbelievable and so disappointing!!!! Rear wheel drive is good in warm climates only or if its only a fun warm weather car!!!!
