Known issue. You have to move the camera around a bit until your 'head' gets stuck inside the fuel tank. Then you can see the bushing. Me personally... I created a new car config (new version) and edited it with Car Editor and changed out the fuel tank and positioning. Plus I corrected the engine swap options since they put the wrong engines as swap options--they don't line up with exhaust components properly.

Edit: If you wanted, you could navigate into the cms game files... down into CMS data\streamingassets\cars\Boltgrandvacances...
right click in a blank area of the explorer window and select 'New'--'Text document'. Now name it config1.txt. Then open / edit it and paste this config data in and save the changes.

Ok, now you have a new van version. Note* You should load this up in Car Editor and be sure everything is lining up properly. You also need to create a new 'bodyconfig1.txt' file to go along with it. You can simply right click the 'bodyconfig.txt' file, choose 'copy', right click somewhere within the folder / file explorer window and choose 'paste.' It'll make a 'bodyconfig (copy) .txt' file. You'll simply rename it to bodyconfig1.txt. You can alter things within it if you like but, there's probably not a lot you can do within that file since this isn't a mod vehicle--limited to games parts.

Ok thanks
