I was lucky enough to order my GN.
I ordered it through a small town Iowa independent dealer, GMC, Chrysler and Buick.
We saw the same salesman my dad bought a new 2wd Ford F-250 from in ‘69 (different dealership).
We told him we wanted to price out a Grand National, he said “a what”. We dealt with the general manager the whole time.
My car has absolutely no power options, no power seats, no power door locks, no power windows, no power trunk release, no power antenna and no T-tops or sunroof/ moonroof.
It does have a tilt wheel, digital dash, top of the line (UX1) radio and concert sound speakers, carpet floor mats, halogen headlamps, rear window defroster and G80 posi.
It seems tinted windows was an option too.
Of course, being from north Iowa I also ordered a block heater which has never been used, unwrapped or untied.
With aluminum bumper supports from the factory, larger sway bars and aluminum wheels the car weighed 3300 lbs.
I feel most GNs were ordered by the dealership, but that’s just my feeling.
