Ready to purchase a 1998 A6. Need some advice!

[imported_EndangeredBeatz]

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.

I wouldn't count on finding many mods but what I have found has been very pricy!

Seems a bit expensive for its year but audi's can go on forever. My 1998 has done 150K and is in great condition. Just service regulary and its perfect.

I have a 1999 A6 SE saloon.

From personal experience, I would check:

Power is OK - if down or "flatspot", indicative of a failed air flow meter, common fault on this vehicle and AUdi replacement part is about £225.

All windows work OK - electrics prone to getting stuck half way. Apparently can be fixed with new guides, I have yet to do it. Garage will charge circa £220 per window!
