You guys obviously seem to be more on the side of american cars even thou akboss drives a mazda5. Have you considered a camry with 3.0l v6, comfy ride like your wife's but with a little kick. Also the maxima 3.5 v6 is a very comfy ride and does have some balls also, no race car by any means but pretty fun ride. If i had to choose between the maxima and camry i would choose the camry just because maintenance wise it is almost unbeatable but like i said the maxima is much quicker. Only way to really know is for you to test drive them, cars are like movies I may love a movie and you may hate it but the only way to know is to watch it. To each their own opinion.
Good Luck
Phil
