Yeah, I wasn't sold on their sturdiness test, but it does show that even new Webers ARE built more solidly than the cheap competition, at least for the most part. It looks like all the Webers did well on this "test".
A true test of long-term durability would take years. So, I guess we have to go with observations and experiences. I have said before that the biggest problem with the Genesis 300 series since 2005 is the closed-in cart. If you are going to have it closed-in and it is going to be exposed to the elements (especially my local hot, humid salt air) then the components need to be made of high-grade stainless. Ditto for the frame legs, especially if they have casters which almost inevitably clog and hold water leading to critical rust-through failure. This has been the death of many of these grills in my experience. Repair involves replacing the entire frame side - pretty costly.
The only Weber grills that came close to this were the "Platinum" versions of the old Genesis and previous edition of the Summit. The Genesis Platinum really DID have a stainless steel frame, but, unfortunately, a closed in cart made of painted steel. It rusts

. The Summit gets high marks in my book for having a stainless frame AND what appears to be high quality stainless panels and bottom for its closed-in cart. Unfortunately, where the Genesis comes up short on the cart the Summit comes up short on its firebox - a well known problem in that it is not all cast aluminum. The porcelain steel front invariably fails at the place where the burners come in.
I think the ultimate endurance grill would be to take a Genesis Platinum, replace the grates and flavorizers with rcplanebuyer stainless, and remove the cart pieces, replacing them with two stainless tube frames between the legs. Now you have all the advantages of the classic Genesis Silver (same internal design and functionality) with the important benefit of a stainless frame and high quality stainless internals. I have been eyeing a couple of these for sale around me and if they last until after tax season I might try to get a bargain and prove my theory
