Does anyone know if there is a quality difference between OEM BMW top versus an after market (I believe it is a gmph brand)? Some body cut my top. Insurance wants to replace with non-OEM, saying it is comparable. I think it is not the same quality (material, craftsmanship, headliner, window gaskets, etc.). Any one have more info so can strengthen the argument against the use of non-OEM. It is frustrating to say the least!
Thanks for any help you can give.
