[Closed] Pontiac's to start your day,

Something strange about that '58 Bonneville.

My memory and books I have show the words "BONNEVILLE" across the hood, not "Pontiac".

The '55 Convertible with NS plates appears to be based on a Chevrolet....

platform, evidenced by the Chevy shift arm & knob and single exhaust on the left, rather than Pontiac's normal right side tailpipe. Could this be so?

It appears to be a Canadian car, based on Ontario plates.

It also reads "Parisienne" below the tip of the spear, not "Bonneville."

Numerous changes to the Canadian version, eh?

As for me, I'll take the '57, please! Or the '59 Bonnie!

Canadian Pontiacs...

In Canada, the post-WWII Pontiac brand sold well. General Motors cleverly offered a line of full-size Pontiac cars that were styled like U.S market models, but were actually Chevrolets under their skins. Model lineup during this period included the base Strato-Chief, midrange Laurentian, and top-of-the-line Parisienne series. Under their exteriors, however, these cars featured Chevrolet frames, engines, and even dimensions. Interiors (except for instrument panels which were Pontiac-based) were a combination of Chevy and Pontiac styling. During the early 1960s, Pontiacs featured the controversial "X" frame used on the big Chevys, as well as the complete Chevy lineup of OHV straight Sixes, small-block 283 and 327 cubic inch V8s, and the big-block 348 and 409 V8s. This scheme was used well into the 1980s, and the Caprice-based 1984 and later Parisienne made it into U.S. Pontiac showrooms to replace the recently discontinued Bonneville. This strategy helped keep the price of the cars to a minimum, as was needed in the then less-affluent Canadian marketplace. GM of Canada was already building Chevrolets in Ontario; they only needed to stamp Pontiac-styled body skins (these were styled like, but not interchangeable with, US Pontiac body parts) and import Pontiac-specific trim from the United States, to convert these Chevys to Pontiacs. It also reduced the cost of tariffs GM would have needed to pay, had they imported US-market Pontiacs Up North.

GM of Canada also executed right-hand drive versions of Pontiac for export. These cars were popular in Australia, where GM faced competition from the big Ford Galaxie and Dodge Phoenix.

Pontiac dealers in Canada also sold smaller Chevrolet-based cars under the Acadian and Beaumont badges. These models are often referred to as Pontiacs, but in fact were never marketed as such, nor did they ever wear Pontiac badges (although the Acadian and Beaumont emblem was in fact, similar to the Pontiac Arrowhead). However, some Chevrolets were badged as Pontiacs later on in Canada. (Wiki)

Also note the front wheel opening on the 55 Pontiac is flat and squared-off at the top, as on a

Chevrolet, rather than rounded, as on a U.S.-built Pontiac.

That red '59 looks really good.
