From 1904-1907 Oldsmobiles had been made under license in St Catherines. This was the one cylinder Curved Dash Olds Model N, selling for $650.
A couple of years later here is an ad for a real automobile, just after GM took over the company in 1908. Price has gone up a bit- $3000- probably the price of an average house. For comparison, the average wage in Canada was less than $600 per year.
Fast forward to 1985, Oldsmobile had their best year ever, selling nearly 1.1 million vehicles- and the brand was killed off as unprofitable in 2004.
