Selling the Mexican Neon as a Dodge would presumably be to avoid spending the money on a new front fascia and interior since the money has already been spent (remember it's design + tooling). As I understood it, all three. The technical feasibility would be getting the 1.4 turbo into it (manufacturing, engineering if it's not sold that way already) and making it works properly, by which I mean “with an automatic transmission, acting like a normal 2-liter engine, not some crazy thing that’s a slug until it suddenly takes off.”) Also, if it's not already designed to meet US regulatory needs, can that be done? The C100 was part of the original plan, and it has to meet NCAP, after all. Market feasibility is probably not much of an issue, it would simply be a low-end Dart replacement which they wouldn’t try too hard to make into a 100,000 car/year proposition, figure 30,000 more per year “natural sales.” Keep in mind it is an existing car! Financially, I don’t think it’s an issue other than figuring out the prices. Nearly all the expensive work is done and the factory is there anyway. Testing costs and such are there but it’s balanced by the need to have some sort of inexpensive regular sedan.
