If you drive any of the above cars and you can't achieve those speeds, then something might be wrong with your engine or car. Better check it out.

Anyway, it takes very long time and long strect of road to reach those speeds
(the speedo neddle crawls like a snail )

PS : I've owned 2 of the above cars before and have touched those speeds, but it takes so long to reach that speed, I almost fell asleep and my right leg got cramped from pressing the accelerator pedal to the max for too long :P.
