The rainbow interior lighting is the coolest, weirdest feature!
It drives really smooth, and really quiet! The interior is a lot more spacious than you'd expect from a car that small. All my passengers comment on how comfortable the seats are. All the little details are really nice, like the little light that comes on under your door when you open it, and the rainbow colors you can select for your interior lighting. The warning chime is also a pleasant reminder, not a nerve-grinding bell. The sound system is also very nice. It has a wide range for volume and the bass sounds great! I like the on-wheel controls too, which is very helpful because mine is a manual transmission. The air conditioning system is also very quiet, and very efficient. You can only set it in 2 degree increments, which is a little strange, but works great otherwise. I have had some early issues with the fuel pump, and fuel sensor. I have also had to have the transfer case replace at ~60k miles, which my mechanic said is "pretty normal" on the Mini Cooper countryman all-4 models. My primary complaint is the lack of cupholders! The two cupholders in the driver's center console are not a normal size, so most cups will not fit. None of my travel mugs will fit, and forget about fast food or coffee cups. They are also very "stiff" and have these spring loaded fins that guarantee your cup will get crushed trying to put it in. There are no cupholders in the back seat which passengers complain about a lot.
