Not a wagon, but a very original, reasonably priced and loaded 1970s Buick worth a look! http://orlando.craigslist.org/cto/4305574718.html
Beautiful sedan. Mind, I would prefer the 4 door hardtop, but this one is really well equipped, and in very good original condition.
A LeSabre Custom, equipped more like an Electra...... I seem to recall that '76 was about the time where you started seeing the options content being ramped up - higher % of power windows/locks ordered, moonroofs, etc. Heck, my M.I.L. bought a Chevy Nova coupe that year, and it had a vinyl roof, power windows, A/C. Still had the 250 straight 6 though! Side note: Isn't the 'Cars & Trucks' section for non-wagon ads?
Nothing but whitewalls would look good on this car. I hate white letter tires on luxury cars, especially classics.
