Purchase of Colt CZ3

Hello together, my partner and I may want to buy a CZ3 with 95 HP. We have already done a first test drive, but have a few questions about the car: How often does the car have to be inspected? In “Ciao.de” I have read that in the first three years you have to have an inspection every 10,000 km to maintain the guarantee. Is that true?? Since we are many times (up to 30000km a year) the inspection costs are also interesting. are these on average? Basically we drive quite moderately. Our old car, an A2 with 75 petrol hp, we have always driven around the 6 liters to 100km. The consumption thus corresponded to the brochure. Can one assume there also from the Colt? Our current car, a Ford Fiesta, needs despite moderate driving mode about 10% more than predetermined. What is the driving behavior in winter? Since we live in Upper Bavaria, does it have here sometimes a few cm more snow than in rest of Germany? Colt somehow makes the optical impression as if they did not last long (although I also sat very comfortable with 1.87m size and just under 90kg). Has someone had experiences with it? So. Questions about questions. We are grateful about every answer and would also be very happy about tips and buying impulses.
