Shame...this machine is in really good condition. I would probably do $650, but I'm not haggling with some yokel who thinks hes sitting on the Mona Lisa. Said he had 2 guys coming out to look at the machine. Kudos to him if he's gets his asking price. 
Well - you can always do the old "Here's my price and my number" routine.   It does look to be in good condition, but I would be wary of the ad saying it is ice cold and the seller telling you otherwise.   
I really do like my V80, I like the look.  It is also much more quiet than my newer CS-96e, but it is a single-vend which is a bit of a downer.   I do think it's cool that it has no knobs or buttons.  Drop your dime in and out comes your Coke.  I love the mechanics of these older machines.  You would also need shims to enable it to vend the 'modern' 8 oz Coke bottles, but that is a trivial thing.   I used a $5 sheet of coroplast to make mine in about 10 minutes.    
It's also an early first-year model being all red (if it hasn't been repainted) which, oddly enough, I believe are not actually as 'desirable' as the later red and white models.
