Hey everybody, I'm currently in the search for an Audi but I don't know much about them other than I really like them. I'm just wondering what things I should be looking/watching out for. I've been looking at 00 and 01 A4s and A6s with over 100k mainly cuz that's what I can afford, but I'm just not sure which is better. Is there a big difference between 00s and 01s? And I'm assuming the A4 and A6 are similar, with the A4 getting better gas mileage and the A6 have more power. Is this right? Sorry that my questions are elementary, but I've only recently started looking into them and figured this would be a good place to start learning. Any feedback is much appreciated.
