RRSport - vibration when cold - is this normal?

[Angelis]

Test drove a 4.4 V8 RRS today and whilst sitting in the passenger seat felt vibration from the seat bottom. At first I thought it was the seat itself on vibrate mode, but it only happened whilst the car was stationary. Once warmed up, the vibration disappeared.

I assume this is not normal?
