Honestly, I think you should keep the 6, especially since they are offering nothing for it......I had the same issue as you. Needed a bigger car cause I play hockey, golf, race etc.....So instead of getting rid of my baby, I wen't out and found a deal on a 98 Chevy Tahoe. I LOVE the thing!! Bought it for $3800 with 155k (178k on it now) on it and it runs great! I had to put about 1000 more into it eventually, but it's worth it. You can find some great deals on old SUV's like that......
