Liked the '70 Bonne hardtop. But my fave of that group was definitely the '63 Wildcat.
(Funny... I didn't notice they were Canucks until they mentioned the mileage in Km... then I detected it right off.)
Was never really a fan of the early '60s GM exterior styling (C2 Vette being an obvious exception), but I did like that Buick. B-body hardtops of that era were decent.
Brings back memories. I remember my Grandpa had a '64 Catalina, in aquamarine. No, not the cool looking hardtop coupe, or the sexy ragtop, or even the 4-door hardtop... but the comparatively ugly 4-post sedan. He drove it forever & passed it on to my aunt, when she got her license. First car I ever 'worked on'... he let me lube it when I was prolly 7-8yrs old. Had a 389, which was the 'base' engine... but a very pedestrian 2bbl carb. My favorite part of that car was the dash, with its sweep bar speedo. (while I was non-plussed by the bodies, I did like the interiors. Go figure)
(in Canada, these were badged as the 'Laurentian' -- although I don't know if they were sold there before the '65 restyle (in retrospect, how I wish Gramps had waited one more year to buy his!)
