Autotrader, insurance companies even Skoda dealers mix and match the terms RS and vRS. In mainland Europe they are all just RS.
As for the options... Xenons would be nice and are a costly retro fit, for me they wouldn't be a deal breaker.
Rear parking sensors again would be good, you can see bugger all out of the back and its bum does stick out a bit with the large rear overhang. I don't have them but I would quite like them... just not enough to get them retrofitted.
Cruise, for me essential BUT retrofittable without too much fuss.
Other than that it is just the sunroof that was a option (and not a very popular one) which I wouldn't worry about TBH.
