Hi there! I am interested in this bike but your listing already says don't be one of those idiots and send me a low ball offer. So is there room for negotiation here?
Well, there's always an opportunity to negotiate.
Great. So have you used the bike for a long time? 
Yes, I've had it for 2 years.
Is the condition good? I mean, any scratches or scraps?
Well, I never rode it, it's a back up bike, so it's in good shape.
Great. So would you accept $1840 for it?
I don't know if I could accept $1840, as I said in my listing it's worth every penny and much more.
So what's the last you can go?
If you're willing to come by and pick it up, I'd let it go for $1900.
Sure I can do that. Its absolutely not an issue for me! I would definitely accept this offer
Okay, great. I'll have the bike ready.
