Given me to have another choice again, I would get the 85D instead of P85D. A week ago, I was wondering should I get the ludicrous mode upgrade, now I am quite certain I don't need that. I drive to work everyday, most of the time I am battling with is not Ferraris or McLarens, but Toyota Crown Taxis try to cut your lane right at the tunnel entrance. And the wide but fast didn't give me any advantage over them.
Many thanks for the above to assure that my decision for a 85D. My only remaining question is: should I take the autopilot convenience features and/or the ultra HiFi Sound option(s)?
