Purchase advice Cayenne engine equipment experience

Hello, I wanted to listen to your experiences and suggestions for Porsche Cayenne 2 or possibly 3. I’m a bit unsure about the engine. I actually had the V8 Diesel in mind but whether it will cope with the many short distances The car will very likely see 3/4 city and country road. Sometimes longer distances (200-2500km). Know me only partially with the equipment, am open to everything. Important would be a long life without big problems. HiFi would be desirable, but I could retrofit something. Is the Approved warranty also worth it? Especially if you extended it? Would most of the maintenance etc do itself or with known or friends Audi mechanics (sometimes only passionate hobby screwdrivers) . Can I quite imagine to miss the car level 1 or level 2 software, so that it also attracts well below 150 Price is incidental . Find both the 2 Series Facelift and the 3 Series Model very chic. High mileage does not deter me, but the maintenance and substance must be right. Thank you very much.
