If you really want the manual, switch the car. Life's too short. F30 is a great daily driver. Interior and in cabin tech is much improved. I daily drove an E90 for 4 years and it was a great car, but I like F30 better
By the way, the best would be to keep the 07 335 and take advantage of the cheap swap to LSD and go to full bolts on to max out the N54. When the turbos fail which to RB turbos
