Hi,
This thing has been around for a couple of years IIRC, I 1st saw prototype pics back then and the price was $5k, so don't look for it to go down much, if at all. The Manufacturer is Swiss I believe.
It looks OK, but personally, I don't care for it. I think it's for Cayman wannabes, which I'm not. But, I suspect there may be a few amongst us, guys who couldn't afford a New Cayman, so settled for a used Boxster. Then there are the guys who can't leave well enough alone or those who have to have every new gizmo on the Market, which is OK and probably exactly who this piece is directed to. But, even with the disparity of the $ vs the €, the manufacturer is getting a pretty healthy markup for a fibreglass roof and some rear glass - you can buy a whole lot of other upgrades for $5500.
My main concern would be rattles and noise, I'm sure there are some. At an acceptable level - Who knows? And then I bet this thing traps a considerable amount of heat radiating from the engine bay, remember how warm the Trunk gets? I don't want to have to run my AC everytime I start it up. So what's next, an optional Sunroof?
I dunno, for me, it's just not something I gotta have...
Happy Motoring!... Jim'99
