Scott Addict SL Dura Ace. Should it be bought?

So I have recently got my other bike stolen which I was very happy for, and I want to hear what people think about this bike, is it a good price or is it too expensive?
I appreciate any advices or help with this. This is a bit over my budget but I thought it was okay.
I offered to buy it for 800 dollars. Any feedback is appreciated

This is his description:
“After having a proper summer ride, this light beauty is now for sale.
Size 56
It is equipped with an almost complete 10 speed Shimano Dura Ace group, except for the crankset, which is Ultegra with oval chainrings.
It rides great and almost by itself, all bearings are great and nothing needs to be done to it.
The handlebars, stem and seatpost are all from the Ritchey brand.
The wheelset is Mavic Ksyrium ES. Really light and in great condition.
The chain, cassette and pulley wheel have just been changed recently. This has been ridden less than 10km.

It is well suited for fast commuting, trying out the sport, winter racing or if you are into the slightly more retro groups like myself.”
