Purchase advice Lupo 3l

Hello, after the fuel prices will slowly settle in with the demands of the Greens and my age is a bit old now I plan to buy a used Lupo 3l. At 60000km a year he calculates himself slowly. Up to now I always drove Nissan, would also like to stay with it, but such a economical car builds only VW. Therefore I have some questions: 1. As so far Japan drivers the most important question: What about the reliability? Golf IV and Co were No highlights of German quality. Is this – hopefully not – also true on the Lupo? 2. Which year of construction is recommended? 3. When is the timing belt change due or other major repairs? And what are these costs, especially compared to “normal” Lupos? 4. Is it only automatic? 5. Are the 3 liters realistic and at what speed? 6. What does it look like with long-distance comfort? Thanks in advance.
