I have both and looking at the 2015's i dont see me upgrading ? Looks the same

 

That's because the 2015 is the last year for the 3rd generation RX. Don't expect any real changes as Lexus were more focused on the upcoming 2016 model.

 

There are only minor differences in the models -- e.g. 2015 has a one-touch turn signal that will flash the light a pre-determined number of times. Small things like that you'll find discussed in previous threads throughout. Otherwise, as Henry says, 2015s are end of the generation and all the hoopla is in the 2016.

 

I don't know about American models, however, Canadian models are called "sport design" and have a much better lower fascia then previous years of Rx's.
