Is this a good deal?

A buddy of mine is selling a polygon d5, fully custom and tricked out for £500. he said it’s been listed at £600 and hasn’t sold, wondering if it’s really worth this much?

this is what he sent me
“
140mm travel up front an 140 in the rear i believe i can’t remember exactly specs as haven’t been riding recently
giant, dropper post
nukeproof horizon wheels 27.5
advant X drivetrain
rockshox monarch plus
cromag bars
rockshox recon air forks thru axle 140mm”

and offered me some other parts for free i can pick out. good deal or give it a pass?
