Any records on what dealership sold it? Looks to be in excellent condition.

I have all original documentation including bill of sale, window sticker, and a 1978 brochure.

Dealer was Earl Olds on Brookpark Rd, Cleveland OH

That’s where my dad bought his first nice car from back in 1983. An Olds Toronado with the smaller V8 in light taupe color, oem darker taupe half vinyl roof, wire wheels. I remember back in 87 when Spitzer Buick had about 6 Grand Nationals in front that weren’t selling too fast. My friend bought a black 87 Regal t type that he still has from Toth Buick that used to be by the airport. I thought it was a GN except the seats aren’t two tone in color.
