2/ Does the vibration eminate from the centre of the car, or is it say more foward sounding, or rearward, Centre or all round the car?

3/Presuming the car's an Auto, Does the vibration occur from a Standing Start?

All these Questions Have Different Answers, Hence Why I ask you to be a little more specific. It could be as simple as needing your wheels balanced on the other hand........

Vibration between 50-60mph is very common. Some people report success in fixing it by having the wheels balanced on a Hunter machine. I suspect that this prevents the vibration from starting as easily, but may not address the underlying problem. Personally, I found that changing the upper control arm bushings, freeing a sticking caliper and renewing the front brake disks (rotors) for good measure worked 100%. There are plenty of other peoples reports in the archives.

Good luck.
