Very enjoyable to drive but really a 2 seater
 I truly enjoy driving this car.  The handling and acceleration are wonderful.  Exhilarating.   was disappointed that Android Auto is not enabled, but I can connect via Bluetooth.  Tire wear does appear to be a concern as there is a sticker from BMW on the windshield to expect 20k or less.  When tires run more than $1300/set of 4 it is a consideration for cost of maintenance.  There is also no spare, so get run flats or risk getting stuck.  At my height, no one can sit behind me, and as long as your passenger is small, you could travel with 2 passengers.  No one buys this car to share the experience with more than one, and I love my BMW.  I would buy it again.  It is a wonderful car to drive and makes me smile every day.
