If you go to the VW configurator you’ll be able to compare what’s included over the other Tiguans ie SEL/Match etc
i would have posted it but it’s pages n pages
But when it changed from R line to R line tech I think they added the keyless entry/Start , 360 degree camera , 2 way control of the tailgate via your remote , a new AID ( virtual cockpit ) and a few other useful things
which was a bonus for all us who ordered one considering it was already pretty well equipped
plenty of Arnold Sharks near you ?
you should pop in and get a feel for it!
