BUST! Barb and I went over to get the brand new never used E310. Open the lid and the SS grates are discolored along with the F Bars with burnt on crud on them and pulled out the grease tray and it had cooked on crud on it too.
Larry was right, new to some is not used much.
If it was NG I might have gone for it. I looked at the manifold and no port for the side burner. So doing the manifold swap was going to be a PITA.
Barb and I talked and agreed there is absolutely nothing wrong with our existing E320, just put new CI grates on it.
So we walked away.
I just looked at the ad again, he's changed the ad to say slightly used and lowered the price to $250 from $500. That would be a good deal for someone wanting a propane grill because it was in good shape.
