I myself don't know whether such a shop exists here in Belgium. But JC-S60 (Belgian to) recommended www.carTFT.com.
I have bought a lot of my parts from www.myelectronics.nl. But in general Germany is cheaper to buy electronic devices from. So suggest you certainly take a look at the first link.
BTW where are you from?
Why is it drug addicts and computer afficionados are both called users?
I work for VCG as a freelance consultant, so unfortunately I don't have the discount the normal employees have on Volvo's and the other Ford brands.
But anyway, even with a big discount on a XC90, i'd still go for the Touareg, it's a fantastic ride and looks great compared to the XC90!
On the other hand, Volvo's might be built better, especially the new S40 and V50, the S60 and some V70 and XC70, since they're made in Gent!
