Wonder how many original owners might belong to this site. I bought my 89 shortbed Comanche (SporTruck, 4.0 w/ 5 speed) brand new in March of 89, at Renton Jeep in Renton WA. Always been garaged, has 49k original miles today (legit). Not only do I still have the owners manual and window sticker in the glovebox, but I've got the original color brochure of the 89 Jeep lineup ('The Jeep Book') that I snagged at the dealership when I took delivery.
One quirky thing from back then - the passenger side mirror was an option. Go figure that.
