    What do you think is the best way to maximize longevity of a convertible top? Should I keep it up or down- it's always garaged.

    I'm going to speculate up, on the rationale that over the long haul, say 10 or 20 or more years, the material will dry out or age or whatever, and lose flexibility. Presuming the top material does age and lose flexibility (whatever it's made of), if it's folded up/creased in the top-down position long enough, perhaps it wouldn't even want to stretch back over the top frame in top-up, or rip, if the top motors/frame were strong enough. That's just a guess, perhaps others will have specific insight or experience.

    Color me three.

    When raised, the top experiences the same environment. If down and packed underneath a cover (or not), its much more subject to damage due to humidity build-up, etc. I have owned 3 ragtop convertibles over the years (now I have a 328i drop-top).

    My wife has an 05 Mini convertible, and fortunately, her car sits in a covered garage both at work and at home. I would say her top looks as if its in better shape than some of the ones on the cars I have seen sitting on the lot at the local dealership.

    She does put some effort into keeping it up, using the suggested products for cleaning and waterproofing sold by Mini/BMW.

    And, no question...The interior will stay in better shape with the top up .vs. down, even if garaged, unless the garage is climate-controlled.

    But, I wouldn't become OCD about raising it. Leaving it down for a few days at the time when you're enjoying good weather won't make much difference at all.

    Definitely up in the garage. It keeps the top stretched out and keeps out dirt.

    I have a 1987 325ic which is on its second top. The biggest factor on longevity is keeping the top out of the sun. Folding is a secondary issue.

    If M6es have a plastic window, they get hazy, harden and crack before the fabric goes bad.

    My vote is to store top-up for all the above reasons plus, as the window slowly hardens, it seems to shrink too. It is probably better to keep it taut in the open position.

    I travel a lot (... as he writes from Lagos, Nigeria) (36 hour layover in Munich starting Saturday!!) and put my top up if gone for more than a week or so.

    Still struggling for ideas...

    I only travel with carry-on bags, so I doubt I can sneek on bumpers or a manifold.

    It seems popular alternatives are to lounge buck naked in Englisher Garten or to drink too much beer and conduct the Oompa band at the Hofbrauhaus. I niether have sufficient sunscreen along or capacity for beer.

    Take some time to visit Salzburg, Austria. Lots of history in that area (especially WWII related) and it isn't that far from Munich.
