Engine Manufacturer

I would like to stop engine manufacturing and look for a high level producer of engines. When starting developing my engine I had no reason to expect the upcoming existence of level 40 managers. So I wish I now had the possibility to stop producing my engine and look for a better one.

It really sucks that there are 10 more levels now. I was level 25. I had only 5 more levels to go ti have a maxed out engine and finally start getting customers. Now I have 15 more levels to do, I will never be able to get a profit from my engine 

Yes please let us do this or at least be able to stop using our engines yet still have to produce them for our customers if we have them
