Things missing from new mechanic menu

A lot of things that could be done to car previously is now not able to be done with the new mechanic customization menu.

From a few I have found.

• You can’t change the interior colour of cars

• On the new import dominator 645 the soft top roof can’t come off

• I believe I saw someone mention something about certain wheels are missing

There might be more things missing but these are what I know of.
