There might be one for fixing jammed rear blinds somewhere.

I agree there is a staggering difference in refinement between early and late cars - the only definite changes were the thinner carpet and omission of the parcel shelf soundproofing, but I think I also read somewhere that thinner door cards were used on non-PPD cars. I also think the boot carpet was much thinner on later models, but it is hard to find out exactly what changed over the years.

Thanks again, and I'll keep you posted

When you pointed out that parcel shelf soundproofing was deleted, i checked the project drive thread with the dates, and my July 2002 auto shouldnt have it. So i stripped out the parcel shelf plastic covers, and the pillar covers and started to take the shelf out, but when i lifted it at the front i found that the insulation is there already.

Maybe it was put back by a previous owner.

My approach to soundproofing is to tap on the panel with my knuckles and if it makes a tinny sound i slap some silent coat on. I did find that the 2 pillars for the roof were quite tinny so treated them while the covers were off. Makes me think the roof panel might benefit from treatment in the future.

As far as i can tell now, the only real difference between my pre-project drive and my post project drive cars noise wise is that the exhaust booms a bit more on the later car having only the 2 boxes in it.

That's interesting David

Was July 2002 the registration or the manufacturing date of your car ? Some cars can have a manufacturing date several months earlier than their registration date depending on how long they were kept at the factory/distributors/dealers etc. before being registered/sold.

How hard did you find it to remove the parcel shelf - did you follow the 'how to' for the rear sun blinds ?

cheers

No need to remove the rear shelve to see if the sound proofing is there.

My 2005 75 diesel has it too,

klarzy · 12th February 2016, 15:58

my 2004 it is there...

Perhaps the project drive info. we have is out of date - perhaps the parcel shelf sound proofing was added back for the facelifts (or just on diesels ??) Either way, I am not going to worry now about putting extra deadening under the shelf - I will concentrate on the doors and under the carpet (with possible addition of PPD carpet if I can find a decent one).

Cheers

Ive pulled a 2001 Rover 75 to bits once and the carpet on the floor did have a good thick slab of sound proofing in it as compared to my 2003.
As pointed out the date of manufacture and registration can differ alot.
Ive owned a late 2002 Rover 75 that was infact manufactured April 2001 but given it had to be sent to Australia it makes some sense, thus it still had all the good gear build wise in it.
Seems over here mid / late 2003 cars started the have the cut backs on materials.
