Hey there! Heard you were interested in purchasing my Marin Coast Trail bike
how old are the tires?
Got them changed two months ago, they're 26 x 1.95 inch Kenda Krossplus tires
Was there a chain guard with the bike?
No there isn't, she's an older gal. 
Would you do fifty?
I was planning on selling it for around $150, used to ride a lot and kept the bike well maintained. New job and everything so haven't really had the chance to ride anymore. Since the chain guard is missing I'd be happy to go down to $100
It would be just parts for me, $50 is all it is worth to me.
Eh afraid I can't do that. If you'd come pick it up I'd do $75 to save myself the hassle
OK, I can pick it up. $75.00
