Ok, it's not a z4 but it's still a zed-been out today sourcing a hardtop for Mrs smartbears z3.
Very pleased as it seems to reduce the wind roar and also subtely alters the look of the car & gives it a coupe look.
Makes me want my z3 back but do like the more modern interior of my 4 shame though would rather have both, mine was deep purple with cream interior although used to get a stream of water on my right leg when it rained, and don't miss driving with a bath towel on my leg haha
