I think you have the 0-60 figure wrong. It should be around 9.5.
although 9.5 seems slow when you drive it you will be surprised. It pulls.
The car is fast and when I had it 71 280sel 4.5 I had no problem what so ever on the highways. It is fast from 60 >> and up. I had it up to 110-115 but my front suspension was not up to spec so I slowed it down. It would definitelly go higher.
