Well, because there was so much heavy-duty vacuuming to be done, I went out and got a small Shop-Vac to deal deal with it all. I got every piece of glass from down inside the door and under the seats. Also, I cleaned up the engine bay and any other place where there were accumulations of crud. Looking a bit better now, sorry no pics of the vacuuming
Instead, here is a photo of the original dealer sticker from the trunk lid. The dealer was J. J. Stewart Motors of Norwood, Ontario. It is unclear whether this is the original dealer or a used car dealer from later in the vehicle’s life, but nevertheless here is the decal, with a nice patina. [UPDATE: it is the original dealer]
My car needs a really, really thorough bath!
