I have a very, very late build Rover 75 CDTi. It has full wheel arch liners, underbonnet and bulkhead soundproofing - and full boot carpeting. In fact the carpet over the spare wheel is twice as thick as that on my (just sold and much missed!) Cowley V6. I have added an engine undertray (not present when I bought the car) and some thick rubber mats front and rear. I have noticed that there is no sound insulation under the rear parcel shelf, but there is foam at the front of it. In terms of improving the sound deadening I had thought of adding some foam around the (full size) spare wheel and some black felt in the door bins. Short of adding deadening to the inside of the doors, I just wondered if Members might suggest any other insulation areas?? ED
