There is a situation. I made an advanced Roadster, it is very hard to finish the deformation. While i was working on it, i started making an even better Honda sedan. If i finish and upload the Honda before the Roadster, the Roadster will never be uploaded. (I want my cars in order at my profile, latest is the best.) Both of these cars took a very long time to make, and i'm not even finished. All of you simply have to accept that i don't want or can work 24/7 on these projects.
The Nissan 370Z Roadster and the Honda City will probably never be uploaded. Together i have started to make 9 cars after this Volvo, and one of them has a chance of being uploaded:
An old Fiat.
