I have been a Weber user since 2002. What amazes me is that they keep refining the products, but keep the basic recipe. The parts on this 1991 performer are almost all interchangeable with the grills they produce today. The ash sweep, ash catcher, burners, etc.
I have a 2002 OTS, a 2002 silver Genesis, both bought new, and a gas-n-go anywhere, a Weber Q and Jumbo Joe for the camper.
