The carts wear out before the grills. The grill's parts are often easy to replace but the cheap a$$ carts are made of flimsy painted pot metal. You can build an amazing BBQ pit with bricks and throw a grate over it for the price of a Webber. You did say charcoal? Just depends on your property and how much space you can devote to it. Recycled bricks are free! If you know where to look...

A friend did this with bricks/mortar as a surround/support for his original Weber cast aluminum grill box. Then fitted the grill with new replacement cast iron grills and a propane gas “starter fire ring” underneath a rack made to support the charcoal. Light the charcoal with the gas then turn it off. Excellent slow cooker and smoker. The underside of the “box” had to have a metal slide in bottom which can be removed to remove spent ash. Also easily bored air drafting holes (with sliders for air control from an old wood burning stove) completed the drafting system. Pretty good setup and reuse of the 14 year old worn out Weber.
