I’m talking about a 2012 or 2013 SLS AMG Roadster, the last naturally aspirated AMG V8. (You may have noticed the coupe version, because it has gullwing doors, a la the 1955-57 300SL coupe.) I want one but in the end, I am probably too frugal by nature to indulge my itch. And living as I do, on the edge of Washington, DC, with its horrible traffic and terrible road surfaces, it does not make much sense.
