Hi, i do not have an audi, however one is possibly in the future.... cousin's S4 with a big turbo. idk if its a cabriolet or sedan, or what year it its (probably + or - 97 ish). ive searched the net, but its mostly just general dealers wth KBB values... no real idea what an audi is (me neither for that reason, sadly) anyway, what would you say is a reasonable price if its got avg miles? if anyone can help me, it would be greatly appreciated!!!
