You can reserve any type you want. You have not committed to that configuration.
When you get the configuration e-mail, then you have to be serious about your choices.
My advice? Reserve the convertible with every available option today then make the configuration based on pocketbook realities. Don't skimp on the options you select.
I have two. A fully loaded Passion Coupe and a fully loaded Passion Convertible. My wife and I enjoy them both!
