Hi, I'm fairly new to this and I was wondering if this used Bianchi Pista is worth 900???

This is what the ad said:
Blue Bianchi Pista frame, deep v wheels with machine side walls

Nitto123 drop bars
46/17 gear ratio with flip flop
All parts (wheelset, crankset, etc) have not been ridden
Will include tape, pedals, front brake set, chain

And if it were a good deal, would you guys advise changing this bike into a road bike? I'm not into fixies and this is more in my price range than a brand new bike and it's in my size. Please let me know anything I should know.... Thank you so much!
