Certainly looks similar, but saying that most of the modern breed of toruing cars look very similar. I wouldn't be suprised if this one was a clone though.
Some interesting cars from that seller though, A full aluminium chassied version of the one you have highlighted and also this interesting looking shaft driven car:
Motor at the front and one of the weirdest designed steering set-ups I have ever seen
One thing I will guarantee is that the quality of that car will be nowhere near as good as the Xray one.
