The notion of an outsider “re-imagining” the legendary Porsche 911 is akin to some new artist designing a colorful new smock and background for the Mona Lisa. (Indeed, the new 991 911 Carrera demonstrates that not even Porsche itself can do it without upsetting at least a few purists.) But as we discovered at a recent gathering in Los Angeles, the idea is not necessarily heretical. In fact, within the first 30 seconds or so of examining Singer Vehicle Design’s fourth 911-based creation, we concluded that its “re-imagination” process produced one of the most mouth-watering 911s we have ever seen.
