Options I would have again for sure (as I tend to have most

)
Xenons - without a doubt
DSG - personal choice
Highline MFD
Autolights (I think are standard anyway)
MFSW
Parking sensors
Nice to have extras:
Sunroof
Foldy mirrors
Armrest
Satnav
Cruise
As for DSG - you read some horror stories but there are loads of these boxes out there and I would have one again, love it. Afterall a small % of anything have problems. I would say YES its reliable.
