Rear double shock failure

My 12k service revealed that both rear shocks are leaking. I had not noticed any real change in the handling of the car until I got it back from the service. The rear now feels as tight as blancmange. Apparently this is due to the shocks fully extending when the car was hoisted during the inspection/service. Lotus have agreed to replace both rear shocks under warranty and Williams will do it on Friday plus a full alignment with laser.Anybody else had this experience with their shocks?

Tomorrow i will go for 1000 miles service.And i want to check shock absorbers because the car really feels to bumpy in the back.Is it normal?the car has 1000 miles!!!
