Powerful diesel for beginners wanted.

Hello, I’m looking for my first car. Since I drive at least 1300km a month I’m thinking if I should buy a diesel. I’m already very interested in the look, the performance and the maintenance costs. I’ve been riding a motorcycle for 1 1/2 years and have already dropped a few percent, which makes the insurance a bit cheaper. I don’t want to have any more like ~250€ a month. I have enough money available Powers but actually do not spend more than 750€ for my car. Since the performance is also very important to me I would like to have an acceleration of 0-100kmh within 9-12 seconds. Aux connection as well as a nice interior equipment should have the car. I think max. 80000, possibly 100000km mileage are acceptable. Does anyone have an idea? Thank you!!
