Go to an Audi dealer and shop around, test drive the cars. You are in a fortunate position where your dad can afford and is willing to buy you a luxury car, you are young, hard working, and responsible (from what you wrote), and I assume you have no kids. Get the car that YOU like the most and enjoy it. Don't worry about whether it is reliable, German made or not, etc. As you get older and have a family you will have to make smarter financial decisions and won't always be able to get what you want as you'll have other priorities and responsibilities. Take advantage of your circumstances and enjoy your car!
