Smart Forfour 1.5 cdi Diesel purchase advice

Hello guys, I’ve already opened up other topics, because it’s about buying a (new) used one. Who has the experience with the 1.5 diesel? Have I picked out a vehicle like this. It has 37,000 kilometers and is built in 2004 and costs 9400 €. Do you think that the car is also worth its HOHEN price? Are these small smart motors and gears denna such reliable? How expensive are workshop repairs there? If you can say more about it, then just write it. I want to know everything about the vehicle. Greeting Blackdriver
