So... You can't use a duplicated car, it doesn't show up in CM and isn't even its own model ? What's the purpose of this, really ? Without a doubt the most useless mod of 2020. Really.
Could've been a 5/5 if this car was a standalone. Shame.
Okay mate. You shouldn't use a duplicated car. The extension shouldn't show up in CM. And no it IS our own model. Try to read the instructions and FOLLOW them. If you find any issue we will try to help you. But denounce features of the mod we didnt announce is a bit ridiculous.
