Car mesh falls through the floor

[BIGHEAD_RIPOFF (BIGHEAD_RIPOFFWX)]

I am trying to make a different vehicle with a different MeshPart (the Meshes are not made by me but are instead taken from a free car mesh pack in the toolbox.)

The car on the left is fine however the car on the right isn’t fine because its mesh falls through the floor also the meshes are CanCollide false so players can actually enter it.

I have found no solutions at all so any help is appreciated.

Could be wrong, but if I’m not mistaken chassis are held in by welds with raycast. Try welding some with springs and constraints.

I have since solved it using Motor6D’s and a different mesh however thank you for your help!
