I can't imagine it does any good for the environment, at least not until >five years from now. Producing a car isn't exactly easy on the environment, and requiring people to buy new cars isn't going to help.
How about locally hand-built wooden furniture from sustainably managed forest - it sequesters carbon and provides often beautiful goods is relatively labour intensive (good for employment figures) and preserves traditional skills. Well managed forest will preserve the natural living environment of many species.
Bonus points if the carpenter eats a low animal-protein diet.
