One thing...tougher to chip a 4.2 (and then only a marginal gain) than the twin turbo.
Only 20K miles! What is there to think about? One heck of open track/road rally/autocross car to boot!
I'm pushing 90k on the '00. It's been driven hard on long business drives...El Centro in mid-summer to Tahoe through the snow. I've taken it across muddy strawberry fields to avoid UFW strikers, cleaned it up and driven to the best places at night. Not a squeak or rattle, no major mechanical problems.
Audi...assolutely.
