What 55-57 Buick models where built in the Oshawa, Ontario assembly plant

[DOVER]

I have a good freind who is looking for a 55-57 Buick, has to be 2 door fully restored and has to be built in Oshawa. I have found some info on VIN break downs that list the assembly plants but none list the Oshawa plant. Where can I found this info?

During those years, only the Special and Century were built at Oshawa. Here are the 2-door models:

Year Model Description
1955 4411 Special 2-door tourback sedan, 6-passenger
1955 4437 Special 2-door hardtop (Riviera), 6-passenger
1955 4637 Century 2-door hardtop (Riviera), 6-passenger
1956 4411 Special 2-door tourback sedan, 6-passenger
1956 4437 Special 2-door hardtop (Riviera), 6-passenger
1956 4637 Century 2-door hardtop (Riviera), 6-passenger
1957 4411 Special 2-door sedan, 6-passenger
1957 4437 Special 2-door hardtop (Riviera), 6-passenger
1957 4637 Century 2-door hardtop (Riviera), 6-passenger


The serial number format is different for Canada, here is the format for 1955-1957:

1st digit is the last digit of the model year:
5 = 1955
6 = 1956
7 = 1957

2nd digit is the car make:
4 = Buick

3rd digit is the car series:
4 = Special
6 = Century

4th and 5th digits are the model number:
see list above

6th digit is the number of cylinders (1955-1957 only):
8 = V8 (all Buicks were V8’s during these years)

Last five digits are the sequential production number unique to that particular car:
five digits for 1951-1963, starting at 00001 for Oshawa ON
