Purchase decision for the Audi 80. Experiences and help needed!

Hello dear community, my name is Christian and I am 19 years old. I will soon start to study and need a mobile kit. Because my father and my brother Audi drive this remains indispensable to me. I need a car for the small wallet and came across the Audi 80, which is very convincing. (Butget 2000€-300€). For me at the moment a few questions ask themselves, but I hope you can help me there. How expensive is the insurance approx. ung? Location – Neuss (near Ddorf) Percent – 80% Under 23 – Yes Kilometer – 50,000km (estimated) What do you want me to do? I have noticed the quattro and a B4. Can you agree or advise me? Thank you very much!
