I got a call this week to pick up a 1 owner 85 Suburban this week.
I was all excited to get it but it turned out to be a worn out truck with 255K on it that had been sitting since 1998.
It must have been a nice truck back in it's day. Fully loaded 4x4 6.2 diesel. The owner bought it for road trips back and forth to Florida. He claimed it got around 25 MPG's on the trips. In 255K he put 3 trannys in it (700R4's). He said once it hit 250K he just didn't trust it for long distance driving so he parked it for the winter back in 98 when he went to Florida. That spring he could not get it started so it sat ever since.
I thought for sure after 12 years of sitting the brakes would be frozen but it went on the trailer with ease. Not many good parts left on it. The body was rotted, mice got to the interior, so with 255K on the drivetrain, I just junked it. The only thing I saved was the mint GMC grill.
As a future reference point a fully loaded 85 4x4 suburban with a 6.2 diesel weighs in at 5620 LBS on the scale.
