Two things:
a) Colour. Yea, so what? I would understand holding out for the best S2000 colour. But I do not understand buying a completely different car in a different colour entirely to the one you really want because you can't find an orange one or something. It's not as if your £8k Evo or whatever will be Orange, is it?
b) Hardtops. Hardtops are rubbish. They should only be used if you want to keep your convertible on the road in an area where you feel its a bit risky. Otherwise, no hardtops.
The roof on a convertible should be used like an umbrella. If its raining, put it up. At all other times, roof down. Even if its 2c outside on a crisp morning, get that roof down. Thats the great thing about a convertible, you don't need to be sitting in blazing sunshine to enjoy it. There are hundreds of opportunities every year for top down fun almost whatever the weather. As soon as you introduce a stupid hardtop into equation you lose the ability to quickly drop the hood.
