anyone heard of this? Sorry If its a dumb question but someone mentioned it to me.

 

its a dumb question^ lol j/k. no i have never seen a marble box and it would cost some $$ to make one

 

Plus a suspension upgrade.

They might have been talking about a paint job on one as opposed to being made of it.

 

i was thinking its wood that is laminated marble look. like a counter top

 

i think i saw someone doing that , and it was paint in diferent colors and a guy sanding with newspaper insted of sand paper and painting again
i didn't wait till the end and never saw the result but maybe i will look nice
or take a big rock and cut it to make your box also get some new shocks and springs lol
