You shoulda bought her a Mazda6 and put captain's chairs in it.
Does Mazda still make vans? The MPV? Just add captain's chairs.
How does being 5 feet tall = a need for someplace to rest her arms? Am I missing something? Or is it just something she's gotten used to having? More relaxing while sitting in traffic, maybe?
One thing to consider for sure; she's safer in something bigger like the Yukon if she's in an accident.
