If I buy an Audi A4 in the ‘10-12 range for 15K CAD with 115KMs on it (70k miles), realistically how much will repairs (not counting maintenance) cost me to keep it running until around 250-300k (155-186k miles)?

I know everyone on this sub hates Audi's etc etc. But figure wise how much would this German (un) reliability cost me in extra repairs vs a Camry? Would it really burn a hole in my pocket that deep, and is it really such a nightmare once it breaks 120-140k miles via /r/cars http://ift.tt/2tIlEx2
