These little cars are perfect for commuting. I've put on 60,000 miles since I purchased it and have only had to service the timing belt and clean the intake system due to diesel soot. I was unsure what to expect for maintenance with a diesel, but I've been very satisfied. This car is too small for a family, but has great pickup when driving solo. Get a manual transmission if you are considering this car - the autos are much slower!
The turbocharger, reliable engine, and great fuel economy. I'm expecting to get to 200,000 miles with this car.
The interior items are flimsy (glove box, cup holders, etc.) Improve dealer service - find a good mechanic and you'll be happy.
