It is not a ceramic but I bought a gas grill at Lowe's about 3 years ago and they wanted 20.00 more for the one on the floor put together. I took the boxed one home to save the money and regretted it. It took forever to get it together and we had a ton of packing material to dispose of. If you buy one on the floor assembled just make sure it is put together right and all the nut and bolts are tight, I have seen some with parts put on wrong.
Let us have a drink and by God lets us not think about the things we ain't never going to know about.
