I have a golf, but many of these neat gadgets are interchangeable.
For me and my wife, since I'm 6'2" and she's 5'1" the greatest feature(s) are the adjustablility of
1. the seats
2. the steering column
This is the ONLY car we test drove that we could both find a comfortable position...and fast. Only problem is, whenever we swap driving there is a 45 second lull as we adjust our respective seats.
3. Oh, I like the ability to roll down-up all of the windows using the key from the exterior.
4. Pinch-proof rear windows are great..our Golden retriever would be without a nose if it weren't for this feature
5. I love how the hood holds itself up instead of searching for some "prop" rod to do the holding for you.
6. Three words: drive by wire
7. Electrical power in the hatch/trunk
I also have a list of annoying gadgets:
1. All doors auto lock at 5 mph..or so. I would like them to auto un-lock when I turn off the car. I can't count the number of times I've parked, gotten out, gone to one of the rear doors, and then had to use the key-fob to unlock the doors.
2. Stupid cup-holders block the radio controls and display.
3. On-off switch for the factory radio is too sensitive. I end up shutting the radio off about 10% of the time when I'm adjusting the volume because I hit a bump.
4. lint/dog hair collecting seats
5. They put that little center "flip down" sun visor thing in the car, but they don't make regular sun visors big enough to accomplish much of anything when the sun is coming in the side window
