3 1/2 years come March - bought it for my wife to replace her mini-van, I had an old '90 Suburban at the time.
About a month later, my "Burb was on its last legs, was rusting so bad around the rear barn doors i couldn't even close them if I parked on an angle. Went to the local dealer auction, desperately wanted another 'Burb. Alas, no luck, and since I'd already pulled the registration and insurance, I HAD to buy something to drive home. Saw a '98 Expedition in good shape for cheap, bought that for the interim, until I could find a Suburban for reasonable coin, then sell the Expo.
Well, my wife liked the Expedition better than the Tahoe (Yeah, I know... what the hell do most women know, anyway....), so we switched, I got the 'Hoe, she took the F'ed up Old Rebuilt Dodge.
As much as I like my Tahoe, I'm getting a Suburban when mine dies. Which hopefully won't be for at least a few more years.....
