I guess it depends on the type of top fitted,
I have my top up while driving, maybe a dozen times a year, and I use my car
near on every day, plus I live in Greece, which is considered a very sunny
climate, and I cannot see any noticeable fade on the inside (I presume you
mean that little piece of liner exposed when the top is down).

To be honest Randy, I couldn't really care less if a small amount of the
roof liner was faded anyway, as I mentioned it's only closed, so visible a
few times a year anyway, and if its closed and im in the car, im to busy
driving to notice, if its closed and im out of the car, I can't see it
anyways.

I really can't be arsed unclipping and clipping the cover every time i park
up in a dusty or risky place, your talking what 3 mins ish to get the cover
out the boot and put the cover in place, and maybe only 30 secs to drop the
top only (mines a NA with zippered back window).

And I've got to say, I am now of the opinion it looks really naff and old
fashioned with it on.

But we are all different I guess, what ever floats your boat, im one of
those weirdo's that think the pop up lights are one of the best things to NA
ownership, I think they look awesome, and I still giggle every time they
make new passengers jump, but it seems I am in the minority on Miatanet and
even here.

I hope you find a solution Peer, like Randy said I think your best bet is a
Upholstery shop, but if all the clips are locating there must be some other
problem mate, mine only lifted when (if memory serves) the front four edge
couldn't be made, and even then only at near flat out speeds.

Cheers Mark.
