The OED defines egregious as outstandingly bad as a modern definition and remarkably good as an archaic definition. I think its safe to say the Bentley Packard in the link below fits this definition accurately. We may indeed be at the end of the epoch of the internal combustion engine and we may or may not believe that exhaust fumes generated by consumption of oil and its derivatives has set the environment on a cycle of terminal decline; what we cannot do is fail to marvel at the engineering phenomenon that is Mavis, the Bentley Packard.
I received a link from my cousin-in-law Mike, a fellow petrol head, to the following video and article from the Telegraph. I thoroughly enjoyed reading the article and watching the road test and wanted to share. I only hope you can suppress your eco-guilt sufficiently to fully appreciate the inherent beauty of this gargantuan machine and the wonderful eccentricity of anyone wanting to build it.
