First car wanted ( automatic, sporty )

Good day, Since I will be 18 this year ( June ) and therefore the car purchase is imminent I would like to get some opinions here. In the lead I would like to mention that I prefer 2 seats > 4 seats but nevertheless listen to all suggestions. Usage is relatively irrelevant ( however should amount to a maximum of 20 liters inside the place which I think is very generous). Budget I set alone for the car 50,000 ( Only car, Reperatur, fuel not included). So far I was ( with my parents ). n) with Audi, Mercedes and Bmw and currently I tend most to an Audi R8 that we could buy from an acquaintance (something about budget, new cars would be too expensive here ). Otherwise I found with these manufacturers actually nothing appealing because for example I don’t like the Slk visually. I hope you can still give me some interesting suggestions ( Autokuf in May/June would like to set me now on a brand/model since I currently have time for it). Lg Spri t I mean, of course, in town If the purpose is still worth mentioning : Daily 8km in town and once a week about 100km highway.
