I read an article from Car and Driver that talked about when Mazda ditched the MAZDA6 Wagon (2007?) and how their CUV alternative at that time had less passenger space, less cargo space, less power, got worse fuel mileage and cost more.
My ideal vehicle would be as efficient as possible, while still being practical. I think an Aptera-like vehicle could be made practical.
Also, my buying decisions will have to conform to the popular opinion whether I like it or not. How long will I keep my current cars? 10, 20, 30 years from now, will the only thing I'll be able to buy is a CUV, new or used?
