Stinks that you have to remove your trunk and top cover. That would eliminate the quick conversion back to original for the day.
That's why I prefer the one sold at Stuttgart. It is not needed to remove the trunk and you can just remove it when you want your convertable top down. Unlike the other one, where it is more for people who want a perminate hard top. But I agree, the Zientop looks better.
I absolutely love that zientec top. $5k though is a lot of money, though. It also looks like a lot of work to put it on and take it off, not to mention the boot lid and top cover.
