I've seen a 986 with the Zeintop and been driven in it round rockingham at speed. The fit an finish is very good and there are no buzzes or rattles once the initial first fitting has been carried out. As to why you may want one....the rear visibility is much better than the boxster , it keeps the hood in good condition during the winter , allows for a bigger load area to be used and does look deceptively like a cayman when fitted. The Morris top looks too much like a standard porsche top to even bother about. Personally I dont have the cash to afford both a cayman and a boxster , but I prefer the cayman with the roof and the boxster with the roof down. 4k to own both styles seems a bargain , a cayman for winter and boxster for summer. Forgetting the "trying to look like a cayman" jibe , I think this is the best looking hard top I've ever seen for a convertible since the triumph stag. The 997 hard top looks ungainly , the OEM boxster top just spoils the lines. If you really want the car to look like a cayman, a change of front and rear bumpers, spoiler and side vents is all thats needed. Just remember that the cayman was an evolution of the boxster design..not the other way round !
