No offense intended at all OP! But that's something I'd hope all people selling their Vortechs would put into the sale thread. I know there's a lot of mp10/40 from 2010 still kickin' with lots of life left. But usually 20-30 bucks more will land you a 2014 model. Hell, I've seen mp10wqd's pop up for $175 a few times.
The only issues I've seen in terms of wear & tear on these pumps is the wet side being damaged. Both of the wet sides on these pumps are in excellent condition.
The manufacturer date was from 2011. I'll provide a photo later today when I'm off from work.
