Well Mondak I don't see why your wife could use your Cherokee most of the time then when you go skiing swutch cars with you....and when I have gone skiing in the past I don't stay over a week, I think you wife could last a week with the Tang. If not rent a car or Mini-van! She will probably not be doing a lot of driving so it shouldn't be a big bill at all!
But thats just what I have done in the past.....She had the SUV I had the sport car I would go away for a weekend (4 days) of Skiing in B.C. most of the time she would use my car but when we had my daughter she couldn't drive the 5-spd so I rented her a mini-van
