Hello, I'm thinking about purchasing a 1997 Audi A4 2.8 Quattro 5 Speed. I have a couple of questions about this car please HELP! 1) is it fast? 2)how can It be made faster 3) Does it come with Turbo? Because I've seen other A4's and they come with turbo but idk if the guy just forgot to say it. Help thanks!
