I'm guilty of buying a Rimowa for the looks.
However as I have used it, I have found the quality to be terrific and so is their customer service/support. I've broken a few things and they've always managed to fix them without hassling me for a proof of purchase (a lot companies like to do that), or charging me even for something due my neglect.
Right now it's very much dented and definitely scratched, but I think that gives it character. The aluminium body makes it difficult to over pack, which I like. I have a tendency to make a poly-carbonate bag bulge.
