Scott scale 20

yo-oda

Hi there. I got an offer to buy scott scale 20 full carbon for 650€. I was wondering if that is still good or not because it has 26 inch wheels. I am 189cm tall. The bike looks really good and it is clean. I was wondering if that is good deal or not. I would swap only xt for sram nx or gx and maybe a better wheels. Thank you for your responds.
