I'd just go by sales, meaning that as soon as you see you are overproducing - let the stock build a little, and then cancel one or two lines. Think of it as in real world. You invest in a production line, not knowing if you will be able to sell all the cars. If you do - you invest in one more, if you dont, you stop the production on the one you have till you have sold your inventory. Retooling really is upgrading the line with the "current" technology etc etc. It also means, that if you design a car that requires a lot of production time, you will make (for example) 100 instead of just 2 a month.. May be you need to up the tech level of your cars?
