Middle class saloon searched (30k €)

Hello, I want to get a car in the next half year (first a move is on). The main purpose will be motorway/road, city traffic only sporadically. I estimate annual output at 15k km. I don’t care about brands, I would rather drive something more exotic than the models of ABM & Co. that dominate the road traffic. Wish would be a hatch (dream car A7 is unfortunately above my budget), because they are relatively rare, it may alternatively also be a sportli Basic requirements: – Diesel – Automatic – Leather equipment – Navigation system – Automatic climate control Gernsehen, but ultimately dispensable: – All possible electronic assistants – Good sound system Up to now I had thought of the following models: – Infiniti Q50 (probably only available as a second-hand model) – Mazda 6 – Volvo S60 In addition to the specific modelwah I also have questions about the question of new or used cars and the respective financing. If you have tips or special offers, always with it. You see, I’m quite a beginner and grateful for your help. I hope I haven’t forgotten any important information, otherwise I’ll follow them naturally. Greetings, Hans
