I wouldn't pay much attention to a Z3 owner who was so scared of wetting the soft top they left they hardtop on permanently :)

Jokes aside the point is correct this it is the waterproof lining inside the top that keeps the water out, not the fabric you see on top.

So back on topic I came across this interesting site showing what all the tops are actually made of:
http://www.autogeek.net/co.html

The terminology in the Z3 description is possibly a typo 'anelastomeric' and probably should read 'an elastomeric'. I had to look that one up..

(ĭ-lăs′tə-mər)
n.
Any of various polymers having the elastic properties of natural rubber.

I can only comment on the fact that my Z4 is much quieter than my Z3 when it's chucking down with rain Dino, so I think there must be something in that mate.

The information that members share is invaluable.

Without a check on this site I wouldn't have bought this Z3 or any other one tbh. I was able to find out that the seats could be fixed with £10 bushes, that the water in the filler cap was due to blocked drains, that the slow-ass electric windows are easily repaired and that the servicing on the Z3 is pretty straight forward.

I have been a forum member of many makes and models of cars and what I like is the open welcome and general friendliness . It takes as long sometimes to reply, "this question has been asked a thousand times....use the search engine blah blah blah" rather than memebers getting that moment of glory when they reply first with a likely solution.

The car isn't a daily drive. I'd like it become something that I can use whenever I want, so it will become the one I jump into for trips to football, work, time on my own.........

I do have a car cover for her. the problem is that the car needs to be bone dry before the cover it is put on........

The seats and carpets will hopefully be lifted on Tuesday/Wednesday this week and can stay out of the car for a period of time. It give me a chance to look at the seals, keep an eye where water is coming in. I've bought a couple of the dehumidifier bags which will also help.

Again, I cant stress how helpful all the members on this forum are and that I am looking forward to a busy and long Z3 ownership

Re a cover, I reccomend the lightweight water proof half cover from Classic additions.
It's sits as tight as you like (by shortening the straps) but the material is light enough for air to circulate so the top drys out even with the cover on.
Just make sure the areas where the strap runs over the body are clean to minimize scratches (no need to clean the entire car each time).

A very good investment at £40.

The water ingress in a Z3 can be from so many places (I had water ingress with a hardtop on!) and it can take a while to find all the leaks. So in this weather a quick to use cover is essential (I got mine a couple years back when we have the heavy rains in Kent). I have since sorted all the leaks but this season another has appeared so the cover have come back out of storage to keep the car dry until I sort the latest leak out (probably in spring!)

This looks good. I picked up a cover but wasn't very good. Added to the want list!

That is also the problem if you have a hardtop and no (heated) garage, you have to put it back on when the weather is still fair or your soft top will rot.

Is there a list of usual suspect areas for water ingress? An idiots guide so to speak.....

...the interior is definitely coming out this week.

As in post 20

1 blocked drains top of A pillar
2 overflow from box the intake to the fans for the heater under plastic cover the wiper spindles go through. The drain from this area block and it fills with water.
3 liners for the door cards are not fully sealed all the way round and when water runs past the window seals it finds it's way into the car.( this was our leak).
4 The sealant at the rear of the soft top fails and water runs into the rear of the cabin.

Leaks into the boot are usually 3rd brake light gasket or aerial grommet.
Ours still leaks into the boot from around the drain channel and into the well behind the nearside rear well and floods the tilt alarm so have just removed the drain bung and stays dryish now.

Hope this helps and if there are any further areas please let me know.

Nearly as grumpy today as had trouble with one of neighbours children parking on the grass in front of our house and chewing it all up. Going to play Monopoly soon so might get worse if I don't win:)

Just thought if the car is leaking wouldn't it be best to put the cover on even if it is wet to stop any more water getting in just as short term, as it will be a dry day soon, Tuesday Wednesday should be dry here and the roof doesn't take too long to dry especially if you dry it first with a towel.

Well as a new member I certainly won't be asking any questions given that unfriendly rant! :-(

And just one more rant today and I promise I will stop.
There was a bloke on here last year trying to flog a wind deflector and could not even get the measurement between the pins right and when the member who was interested was told it would fit his car by the seller, and I told him it would not, the seller got rather assy.
Some times you wonder, why do you bother..!!
