put down the estrogen pills and keep the CAR!
all kidding aside, if you already have a Yukon XL, why do you need another family car? Since it costs me about $700-800 a month to drive (car payment, insurance, gas) and i am only 19 with a not so high-end job, i still live at home. i have my camaro, my dad has his mustang, and my mom has her Yukon XL. whenever the whole family goes somewhere, often with a friend or two, we take the Yukon. it seats 7 people. it would have 8 seats, but somehow, it has the pilot seats in the middle row like the denali does, but without the 6.2L denali engine or the inflated denali price.
my car and my dad's car are mainly used for, well, me and my dad, often with one other person in the car, whether it be family or friend. my mom sometimes drives my dad's car whenever she gets bored of driving the "tank" around.
my point is, whenever there are more than 2, 3 at most, riding at the same time, the Yukon is the vehicle that gets used. there is not even a hint of a need for my dad to trade in his car for another SUV, and my family is by no means small.
my car is mine, only driven by me, and it'll be a cold day in hell when i trade it for something with more than 2 doors. then again, i have no plans to start a family any time soon
to each his own i guess, but WHY?!?!
