Hello all, new to Audi world former 2006 XJ VDP Disciple. About to purchase a 2006 A8 L with 93,000 miles for 12000. Price seems like a good deal. Purchased a car fax, shows 4 owners but maint. Seemed consistent except for the last 25,000 miles. No records. Car visually seems to be in great shape. Issues I've found so far I think are minor, such as nav screen gear issue (which the dealer has agreed to take care of) and door soft close passenger side is inoperable. He says that has been deducted from price. Although I have tried to study this site and learn as much as I can, I am still a little apprehensive. Any guidance would be greatly appreciated. Thanks
