Got my (wonderful) SVR back after 6 months off the road waiting for a front ACE pipe.

Driving home from the dealers I thought the suspension felt a bit bouncy/wallowy, but so glad to get the car back I put it down to being in a hire car for 6 months.

Today (2 weeks later) the wife and daughter were in the car for the first time, and within 50 yards said the car was bouncy and wasn't right.

Any ideas on how and what to check? It doesn't feel right, and I've had the car for 9.5 years and done 96k miles, so know it well.
