Looking at them, I'm realizing I didn't look at mine in quite a while

The red one is my father-in-law's. Same coloration around the base as mine, although mine is way worse. That stuff cleans off fairly easily with some E-Z Off and a scrubbing pad, you can see the condition mine is in, and a corner of his, which shows the same coloration, and how it looks after being cleaned on the right side of the red one.
That crap cleans up, and you can see how well all the stuff wears. Notice on the red one the Weber logo is chipped/faded, but the rest of it looks brand new...dunno what they use to keep that paint job lasting so long, but I wish cars looked as good!
Mine has the wood rotted off, his he swapped out with a plastic cutting board type material. All the parts for replacement are easy to find, you can even find some parts at Home Depot, and you should have this thing for a while...we've used his grill to feed a birthday party at his house with all the family - 17 people, 10 of which were adults - and had no problems. Grilling size for what you're usually gonna use 'em for (burgers and hot dogs) is MORE than sufficient. Where you'd run into issues would be steaks, but for 4-6 folks, it wouldn't be a problem.
BTW, I'm fixing up my Weber to take over for my el-cheapo Char-Broil grill, which I'll be "blessing" my brother-in-law with (or if they take trade-ins for parts, using it for that). Until I saw the condition mine and his are in, I always poo-poohed the price for Weber's as "you're just paying for the name". I'll be selling my smoker to replace it with a Weber, they're that good.
