Currently in Vegas with my Golf GTI hire car. It's a Carbon Grey DSG 5 door. Main differences between this and UK spec are: Halogen lights (they're like a pair of candles) no digital climate control, a manual handbrake, no ACC, very soft suspension, parking camera (but no parking sensors) - I'd rather have the sensors, but spaces here are huge as the average car here is a Dodge Ram (huge). It does have an SOS button in the roof console to link you to the breakdown services, front and rear lights are just like you'd get on a Base model Golf. Other than those differences it looks pretty much like a UK model.
So glad my R is manual, the DSG is so dimwitted when left to its own devices. Anyone wondering whether to get an R or a GTI, I'd say get the R, the performance difference is pretty substantial (and it is running on 95, not crappy 91). It's a thirsty bugger too, averaging 21mpg (US gallons), so about 26 miles to the proper gallon.
Going to drive it to the Hoover Dam today.
