Used small car up to 10,000 – new but entry class vs. older but raised

Hello, I would like to know your opinions on the following fundamental question. I am looking for a small second car with a lower annual mileage (max. 18,000 per year), with a budget of 10,000€ Now I am asking myself the principle question whether it would be better to buy a newer one of the “entry class”, e.g. Opel Corsa with EZ 2016, or to use an older used one of the “upgraded class”, e.g. Audi A1 with EZ 2008. It may not be so important to rely on an older model, which was originally more expensive. What about insurance costs? What are your opinions?
