Well you have had Martin's so it would be rude for me to not join after our introduction.
I would agree that if the Zed was my everyday car I would have gone for the Coupe, but having it as a second car and on days like today its definitely the Roadster for me. As long as its not raining I have the top down.
I wouldn't say thta all Roadsters have a roof problem. Not had any major issues with mine and its a 53 plate.
