You have to use a mod that replaces the axles. Check the thread of the I-Series wagon and you will find more info there, the fix for that mod also works for the Miramar wagon. OT:
Wah ! silently "announcing" 3 epic mods ! This will be awesome ! I wonder why there isn’t more likes on this post tbh ^^" OT:
I tried to make a retro restyle Pessima but uhh... ended up making something that doesn't look any older but more "luxe" and fullsize-ish instead, yes it has a V8 (from WBIMP)
You would probably need some mods for it to work, at least 5 and I'm not sure if some parts are from the vanilla game or from some other mod lol, I know for sure you need WBIMP and GPACK but I could have used something from CJD Special Tunes without knowing, and also mods for the lightbar and license plates... idk if it's worth to install so many mods just to play with 2 configs and they don't even drive that good lol
