Thanks, there will never be a car in there, so no issues there.
I can't really build up from the current level more than a little bit, there would be a step up in floor level from exterior to interior. Suppose it could ramp down to the door , but likely stats getting tricky to do.
I wonder if there is any way to cut out some of the bigger bulges there currently, most of the variance in height is limited to some small bulging higher areas
Hire a floor scabbler (a large machine that grinds concrete surfaces) they're loud, dusty and vibrate like hell but they can be used as a plane to level floors, you will need to re-finish the top with sharp sand and cement or a dedicated mortar repair product.
