Because I prefer to be enclosed with the aircon on. Every time I drove a convertible I just felt grubby, dusty and dirty afterwards and taking in everyone fumes. I owned 3 Saab turbos, MX5, BMW 330c and a Honda S2k, I also think that the coupe versions have better lines, hence better looking. I have owned 47 cars to date and I’m sure I will have a few more, just not another convertible!
