I sat in a Highland today at Tesla Stratford. It was a left hand drive model. The interior improvements are nice, esp the mood lights and the ventilated seats. The exterior changes are less obvious than I was expecting. But I think overall it does look a little more stylish at the front than the old model.
The stalks issue is what it is. I'd prefer that Tesla hadn't done it, but if SEXY button people deliver an after-market solution then it's not the end of the world.
Build quality didn't look noticeably better than the current model and while the door shut is a little nicer in its acoustics, it's not night and day IMHO.
Overall, it looks like a nice upgrade, but I don't think I'd be jumping in right now given that there are zero discounts or finance deals available on them.
