I Own A 91,98 Deville , But I Am In The Market For Another Vehicle, A 2000 -02 Deville, But I Notice In My History Of Cadillacs That They Can Cost Alot Of Money To Keep Up, 98 No Problems Yet. 91 To Many Problems. So I Am Also Thinking About A Chevy Avalence(2003). I Know That Chevy's Are Good Cars And Cheaper To Repair, But It's Still Not A Cadillac So What Will You All Do. Deville Or Avalence.

I would personally go with a GMC Yukon or a Gmc 4 door truck, 1st of all chevys/Gmc's have alot less moving parts=less likelihood of problems
2.Avalanche has horrible blind spots and comes with the 6.0, might be a gas guzzler unless you dont care and do some mods to help it out, but on a personal note i live by mechanical simplicity, it will save you more in the long run
