Finning has a large European and South America presence besides Canada which makes it Cat's largest dealership worldwide. But I don't know if their North American ops are larger than any other North American Cat dealership
Having worked for them not so long ago Finning has the following dealerships ........
Western Canada - Alberta, BC, Northwest Territories, & Yukon (4200 employees)
Latin America - Chile, Argentina, Bolivia, & Uruguay (a total of 6600 employees in the 4 countries)
UK - the former Leverton, Bowmaker, & Caledonian Tractor operations in England/Scotland/Wales, & the Mcormick-Macnaughton operations in Ireland. (1600 employees)
So we're looking at over 12,000 employees in 6 countries on 3 continents. I know that's getting away from North America but still worth a comment IMHO.
..... plus they now have the Bucyrus dealerships in all the above territories, bought not so long back from Cat for US$300 million IIRC.
When we talk about "biggest dealer" I guess someone needs to ask how is that decided..... area of territory, number of branches, number of machines sold, number of employees, turnover in $ terms, what ..?
At one time around 10 years or so ago (not sure about now) Zeppelin in Germany was the biggest dealer in terms of machine sales because they had a stranglehold on the construction market & sold literally thousands of small size machines in their terroritory.
At the same time Trakindo the Indonesian Cat Dealer (5500 employees) was the biggest in terms of turnover because of all the large-scale mining operations in Indo plus the fact that almost all the power generation in a country comprised on literally dozens of separate islands is supplied by diesel generators and Trakindo had the lion's share of the sales.
So I guess at the end of the day it comes down to the basis that you use to calculate "the biggest" .........
