Welcome Joe. You could always get an SRT and swap out the seats with some leather seats from a Limited for your Wife.
I'm afraid you're right about your hight being an obstacle. Even though I'm 6'2'', I'm still comfortable driving my coupe. But when ever I ride in the passenger seat, I feel cramped. Personally, I think the only way you would ever be able to ride in her car is with the top down.
