The Gavril Grand Marshal has no roof

I spawned in a Gavril Grand Marshal and the roof is missing...

 

I see mods. Clear cache and try again?

 

Delete The GM Convertible mod. it was packaged the wrong way and overwrites the original body.

 

Try without mods, then if it works fine, try using each mod one by one to see which one is acting up.

 

Took me a while to hunt for the Cabriolet mod folder so I could delete it but it fixed it
