If you feel you might want an "alternative" car someday, either historic, kit built or handmade by a low volume manufacturer, might I respectfully suggest that NOW is a good time to buy.
As advances in technology threaten to bring driverless, petroleum-less, soulless motoring for our everyday practical needs, the demand for alternatives will increase for those who want to express their individuality, or tinker with stuff, or just relive experiences if the past.
