More of the same is not enough to get you to some other faraway place. Making a better car will not result in an airplane. That does not mean that making a car first is not an worthy endeavor for gaining experience to build an airplane - should you need e.g. machining, metalworking and general engineering experience. But it won't give you ANY aerospace background. Or as Alan Mulally famously put it: "An automobile has about 10,000 moving parts, right? An airplane has two million, and it has to stay up in the air." (on being asked "How are you going to tackle something as complex and unfamiliar as the auto business when we are in such tough financial shape?")
