Lowballing in Car For Sale Posts

I will comment and say that I’m up in the air on comments like:

“dude isn’t this the car you rammed into a tree at 65mp?”

Because of course the seller could have and is hiding it ( helps the buyers )

or maybe the comment was made by a jerk off just trying to ruin the sale.

I don’t mind however, when people post things like: “KBB says this” or “you can buy this, here, for so much lower”
