well.... for outstation travelling, F10 is better as it is more comfy and roomier.
Issues? Well, I have had a lot of issues with F10. Thumping absorber (changed not too long ago), squeeky brake, wobbly at high speed even in sport mode, slow wiper compared to 3series, lack of lateral support, air cond not cold enough. I like the hold button and how it layout of buttons on the steering.
320d, i still dun understand how u guys did 1000km. When i filled up max (to the extend of overflowing), the reading showed about 750km till empty. Can yu guys enlighten me on this. U can't say i drive like a mad man since it is still not run in yet so rev below 3k. When i turn, i can hear funny sound from suspension, did you guys feel the same? somehow i cannot synchronise my phone with the car's bluetooth....... need to check with dealer. Overall, the torque is addctive but if possible, I hope BMW can improve on traction a tad better. Hope F30 comes witl hold button which is convenient during jams or whilst waiting at traffic light. The buttons on the steerings are not well thought out. Hope they can standardise it at least putting the volume and song/radio channel on the same side throughout the series as I always press the wrong one when i changed cars.... so it is very annoying. Diesel engine clatter still need some getting use to. Overall, pretty happy with 320d.
