599 is fugly, but don't know a single owner/driver of 599 (of 4-5 599 owners who are colleagues of mine) who can't look past its fugliness (and weak passive safety) after becoming addicted to its tech innovations (esp latest F1 tranny and advanced chassis)/perf/precision/utility....

Problem for P is that its lack of tech advances (esp PDK, solving turbo lag, charismatic exhaust note, etc) will mean buyers will need to rely more on good looks of car to justify purchase.....and, given Panam is still some 2 yrs away, I suspect latest/greatest F/AMG competing models will be moving targets w/further innovations in chassis tech; lighter materials; useable tq; fast/smooth paddleshifter trannies, etc....
