Ditch the Vettes, they're money pits, plus everybody already has them. You're driving a distinctive, relatively rare car and I'm sure more than one person has come up to the vehicle and drooled on it. Right???
The only thing that could be better than having one XF would be to have two lurking in the garage.
Sell the Vettes to the first two damned fools that come along and get another XF. You'll finally be a man among men!
