My case is that the datum line was my old Rover 420sdi. I got the 75 and was delighted with it.......for 13 years. Then got the second one, and it was noticably noisier so i simply set about trying to make it as quiet as the first.

I would say i have taken it 95% of the way and am very happy also with the second car now, but there is still something, and i suspect it to be the doors.

As i had material left over from car 2, i didnt see any harm on using it around the boot on car 1, but as I said it didnt make much difference that time. That is probably because that car does have 3 silencers so there wasnt so much boom from the back box to deaden in the first place.

I have reached the point that car 2 is a little but noisier than car 1, but not really noisy enough for me to make the effort to take all the door panels off again to put sound deadener in, although at some point i may need to replace the lock motor, so if i do i will give it a try.

I guess what i am saying is that for 13 years I agreed with you. If i had only ever driven the second car i would have agreed with you as well. Its only because i had an exceptionally quiet one, then one not so much that i got on to this track, and now have what i think are 2 quiet ones.

Like Jim's case, who would ever inagine a brand new Jag would be noisy? Well if they have had a quiet 75 previous to it then they would, and some of us just want a quiet life and a nagging curiousity to know why things sound different.

I have been in 3 cars of various late models recently with distinctly noisy wheel bearings, and sat there thinking of the drivers, "cant you hear that racket?" But they were oblivious to it, so again as you say sound is in the ear of the beholder. Agreed.
