Yup, just because you don't like their designs doesn't mean they don't create high-end product or aren't capable of sourcing it. The best materials and technology doesn't always come from the factory. Some super expensive development stuff, sure, but a lot of stuff comes from suppliers and craftsman that anyone can contract if the price is right.

If you want the best white leather seats in the world, I assure you there are source beyond Porsche and that Mansory can get it done. Hell, a lot of people can get it done. Do you think some guy spending $1M restoring a $10M Ferrari isn't getting the best stuff money can buy that's at the very least equal to what Porsche would supply?
