We've owned our Weber S-470 since June 2013. Love it and the rotisserie feature. I do have to replace the flavor bars and need to see if I can get the inner rails that they sit on, they are rotting off in a couple of areas. I dismantle the grates and clean out the inner parts at least once a year. Usually at the beginning of spring. I use it about 3-4 times a week, all four seasons. I try to keep it covered when not in use. Food cooks and taste wonderful. We're happy with the purchase.
