Almost positive you are correct. If I save after swapping body code without going to GT Auto I can enter a lobby. If I try to go to track with any combination of regulations it says "Evora TC can only be used with other cars of the same regulation". I haven't tried the same with the others but I'm assuming they will do the same. The really odd part is, you can't sell the car or delete it from garage until you put the stock body code back on. Also, if I get in to one of them, my log says "changed to no such car"
