Ngianop,
The reasoning behind installing the GMC Jimmy interior is my wifes (old) 1998 Jimmy has that interior and she felt so comfortable driving the truck... and after doing some measureing .. along with luck it really fits excellent in the Buick body. Big drink holders and super comforable power seats...
I have long legs and when I put the power seat all the way back I have trouble hitting the gas.

But she can go forward and still be sucking the steering wheel (being so short) ... so the seats are a definate fit.
The center console needs some fitting but it's well worth the work with the drink holders and positive detents, along with good lock outs. Perfect for the Stage Right trans brake that's installed in her car... Just slam it forward out of low 1 and it's in Overdrive.
So, in a nutshell.. we just happend to be driving a truck with the interior we were comfortable with and thought it'd be a good fit in the Buick...
Ryan,
I picked the grey color for the middle and the blue for the outside. They made the power6 on the headrest as I love that look... they do very excellent work. They did the rear seats to match (like GN) and a complete trunk kit... headliner,headrests... and carpeted the center console blue. I painted the rest of the parts base/clear with "mat" clear so it's dull. (like factory) but durable and flexable...
I'm going to paint it and re-assemble.. then she's going to be driving that one too.. Fun for her...

Hope that helps,
Scott...
