Ever seen a Buick owner who doesn't think his combination of options is rare?
Well in Spoolin's defense, as I'm sure you guys already know, late build '87s were "supposedly" cranked out as fast as possible, hard tops, & with what parts were available.
So, in theory, for a late '87 build to have T-tops and a digital dash that was still laying around the parts bin, is unique.
BTW, I'm a stereotypical Buick owner with a rare combo. I have a 1 of 1,595 '87 Canadian export. It has a factory 140 speedo, in KM that is.
