RE: Hard top for convertible ?
Jag hasn't mentioned a separate removable hard-top for the F-Type, but I'm certain the aftermarket will respond with such an accessory if Jaguar themselves do not offer it. The F-Type is going to be a hot car; expect a burgeoning aftermarket.
For some comparison, Boxster owners can buy aftermarket hard-tops for around $3,000. An F-Type removable hard-top should cost around that, if produced.
