After a few years of being Audi-less, I am now the proud owner of a 1990 Audi 100. Affectionally dubbed the "purple slug" by the previous owner (my brother), it took me 4 days (2,200 miles) to drive the car from Seattle to Dallas (ran just fine and didn't eat a single drop of oil!).

The car is pretty much stock, except for a lowered suspension, nicer wheels and European-spec headlamps and window tinting (which is a necessity here in Dallas, TX).

I have also created a book that tells the fascinating history of Audi; it is a self-running ebook (on cd-rom). For more info:

Brief update: November 2007: the car now has over 282,000 miles on it and still runs & looks good!
