def Yes get them.
After having xenons in previous cars , I dont think you can ever go back.
Other option is retro fit xenon packs , which although not strickly legal (no washer/levelling) would prob be ok.
worth it just for the 'flip' when you switch them on

resale , it may get you the sale against an identical spec car , but you are never gonna see a good return.
In fact I had to look at vw website to confirm it was a 750 quid option ! but steep , so I must have REALLY wanted them.
