Hi guys. Well I come from the BMW family have had 3 previous 3 series & just sold my 1997 5 series. I'm looking around & made my decision to purchase either an Audi or a BMW newer body 3 series. I need something roomy so after searching, I found a 1998 A6 with 37,000 mile. Auto. Blue with blue & cream interior, with looks cool as I really never seen another car with that color combo. The only upgrades are brand new 18" Mille Miglia Rims. Price 11,000. I need some help as I know nothing about Audi's? Is that a good deal? Anything I should look for besides the regular functions of a car? Any major defects or known problems with these models? Is the 4WD good in winter conditions? Do they handle good & are they fast? How is the cost of maintance for Audi's compared to BMW (which is pretty high)? Do Audi's hold there value for re-sale? Are there many upgrades that can be done as far as exhaust, intake, lowering, bumpers, etc & is it pricey? Any recommended sites for mods? Sorry for all the questions.........I really need help. Any other "feedback" will be helpful & appreciated. Hope to be a part of the Audi family. See you guys soon. Will keep you posted. Thanks in advance.
