Im considering buying an A6 either the 00 or 01 2.7t with manual transmission.

Is there any major difference between the 2 models ?

Also do I really need one with the sports suspension or the standard good enough ?

Is there anything I should look out for on the 00 or 01 2.7t A6, the resale value seems to be low on older models..

I drive aggressively once in a while when I need to so Im debating the sports package.
