If we do not take this seriously it can be entertaining. Were it to be serious the Model T, Citroën Traction Avant, and a few others would be on this list. For that matter the Audi Le Mans winner was not really the great innovation but common rail was so the Alfa Romeo 156 2.4 JTD would be on this list, if not the even earlier Denso-supplied Hino Rising Ranger.
However, Top Gear is orientated (UK spelling) entirely to bizarre and entertaining absurdities with the odd bit of content snuck in just to be perverse. Thus, their list does well. If they were serious about British the Mini works as does the Defender but what about the Rover 2000?
I do have my personal list drawn from my own past ownership: Honda S600, NSU Ro80, Mazda R100, Rover 2000TC, Maserati Biturbo and finally Tesla P85D. Oddly the only one of my list of "greats" that actually worked well is the Tesla. So, my question is this: for all of us who are professional early adopters of the exotic, how can we explain the tesla when this one actually works?
