So I can release it on the repo. Also if you read through the thread you would see i've said a nissan branded one will happen sometime for the forums.
Not likely, I don't wanna have too many engines since i'd like to have lots of customization for each engine. That doesn't mean no, it could still happen or maybe in an update.
You can't just simply make a car ready to be released that quickly, these things take time so please be patient.
