Wife's car is fixing to crap out again (transmission) and we are being told by multiple mechanics that it would be in our best interest to get rid of it now. She has a Saturn Outlook now and we are thinking that Sequoia, Tahoe, Yukon or Expedition should be next. Likely going used because the thought of paying $50k+ for a car gives us both heartburn. Of those options, which is more bang for your buck? Which should be avoided (reliability, etc...)? Any other thoughts?
