B4 upgrades for B3s

[Spurtboy]

Hi all, total newbie to Passats but I got hold of a nice B3 wagon last week.

My first thought when buying a car is what upgrades from newer models can be used to upgrade it.

With the B3 and B4 being so similar, I wondered if there were any worthwhile upgrades to be had from the newer model?

Cheers
