I have 6 payments left on my 08 V6 lease, then about a $14k payout. I'm 99% paying it off and keeping it, since I freaking love it.
My only concern is, it's been 15 years since I've owned a car (and especially one that wasn't under warranty anymore.) My G8 now has 42k miles on it, so I'll either pay it off and keep it or sell it for a profit. But I'm assuming I'll keep it since I freaking LOVE the car.
I just wish it had bluetooth and nav
