. It's a fantastic engine, makes a ton of HP, makes gobs of torque, is lighter than previous generations, handles like a dream, and gets great gas mileage. The 335i is overkill. Great car, not necessary anymore. The 328i closed the gap too tightly for the 335i to matter anymore.
Rear Wheel Drive
. Own the car the way it was meant to be owned. XDrive is not a way to avoid snow tires
. Very few geographic areas require both XDrive and snow tires
anyway, so its a waste of time and money.
. The base model is missing too many features and too much styling. You need a Sport line or a Luxury line. Start there.
. The LCD screen is the centerpiece of the cockpit and the smaller panel shoved in the larger piece of plastic looks atrocious. The F30 is a technological marvel, one shouldn't skimp on iPhone integration, album art, split screen, streaming audio, and of course the heads-up display.
. Not a BMW option, but if you live where the majority of 3 Series are sold you need good rubber for the winter time. No matter how you build your car, reserve $1200 for this critical safety feature. If it boils down to snow tires
vs. XDrive, you choose the snow tires
. Every time.
. A BMW isn't a BMW without xenon's. Not only is it a signature styling cue, but it is a quantum leap in illumination which enhances performance and safety.
. Lots of goodies in an affordably priced bundle. Comfort access, all the toys, leather.
Rear Camera w/Park Distance Control
. Very helpful, very safe, and BMW's execution is top-notch. If you have kids or live in a city environment it's a can't-miss feature.
. You don't need the winter package, just the seats.
Those are the "must haves". There are no "must considers" because at $50,000 you can afford any option you want and shouldn't drop a feature or two because you want to save a few dollars. Build it the way you want it, spend the money, done.
