Giant TCR Advanced 1 Size M

Hello. Looking to buy my first “race” bike and through my research seems like second hand is the best bang for buck.

Found this giant tcr advanced 1 for 1500€. Is it a good price? It’s sold with the original wheels and not the dtswiss?

Bike is size M and I’m 181cm 80kg.

Anything I should look for or be concerned?
Thanks.
