shaking+shuddering at 45-50mph

Weird. Got a megane scenic auto.

When you get to around 45-50mph the whole car shudders and shakes. Any ideas ?

Tyres have been changed. Tracking and balancing done.

Hmmm. Only at a certain speed? Absolutely no problems at any other speed.

Driveshafts - expensive ?

Renault probably forgot to weld up the floorpan or something. I'm not joking. Any wet carpets?

could be that the driving vibration hits the resonant frequency of the suspension or whatever - that'd certainly account for it being particular to that speed. By rights, you ought to be able to feel something at 90-100 as well, but it could be a particularly heavily damped system that's being excited, in which case it might not be a noticable effect.
