Reliability of Nissan Micra K11???

Hi, I’m looking for a cheap car in maintenance and I came across the Nissan Micra K11, my budget <250€. The used car market already gives something. So now my question is how reliable are the small ones? Was in recent years with my BMW ́s about this topic actually quite well spoiled. But I see it no longer to pay this maintenance!!! I would have had a strong interest in a small engine for the purpose of driving and consumption, am actually a quiet he driver and from there no accelerator junky. How much do they consume? tax? insurance?
