Fair Price for 8's

[hipshot]

Hi guys.
New to forum. New to Audi. I ahve been admiring the 8 for a while now. I just finished modding a 850 ci BMW. Its time for me to buy a daily driver. I cI am curious about 2nd hand prices. Luxury motors dot com seems to have reasonable prices?
What should I be paying for a 8 with sports package, and 30-40k miles on it?
What is annual maintenance like? How much do you guys spend per annum on maintaining yor car?
When do they start to need a LOT of work? 100k miles? 75k?
What should I be looking for when I test drive?

Thanks for the help.
Hip.

Now is a great time to pick up an A8- all the 2006's are coming off lease now, so where as they were in the $40's a couple months ago, you can probably pick up a Certified A8 in the low to mid $30's from an Audi Dealer, then for just $750, you can have all of the maintenance covered to 100,000 miles as well.

Seems like a no-brainer to me.
