Well not really to be honest, most parts can be sourced cheaper even with a little VW trade discount if your happy to use non genuine bits. Personally from my experiance with the golf, genuine bit's ain't up to much anyway, so i just as well give some otehr manufacturers a try and save a few quid at the same time!
It does help though on certain main dealer only parts. Also things like cambelts/ waterpumps/maf's etc I feel easier with using the gen bit's!
Cheers for the comment on picture too
