The car is fun to drive with good performance and fuel economy. I am really impressed by the diesel engine, which puts out 177hp and serious torque from 2 liters, while keeping consumption on average 6 l/100 km. Even urban driving hardly goes over 6.5 l/100. On German autobahns 200 km/h is easily maintainable and ride comfort is not degraded.
I'm really fond of adaptive xenon high beams - the car switches high beams on automatically when you drive outside cities and when there's no other drivers around to bother. The precision this system works is amazing.
On the other end are the automatic windscreen wipers. Their behaviour could be described as random, unpredictable and funny. Sometimes they wait till I cannot see any more in the rain, other times they continue scratching over dry glass for 1-2 minutes.
Run flats have their pros and cons. The car by design has no space in the trunk to put the spare tire. I recently drove about 1500 km through Europe, and the tire pressure monitor warned me for losing pressure. I stopped at a gas station and checked the tires, one of them was just below, so I pumped it, and in the next few days drove another 250 km until the next warning. Then after a bit more serious investigation I found there was a nail stuck. Replacing both rear tires 225/45/17 is painful for your pocket, but at least you have some confidence you won't have a serious accident if it happens on the motorway.
The trunk space is not the greatest that you would expect, but considering the rear wheel arches reside almost fully in the trunk it is good enough. Also the front wheels are on the very front of the car and this gives great stability curving.
