From what I can tell, this may be a record year for car sales in Belgium. Recession? What recession? The last few years have seen the lead change often and this year did not disappoint. VW pipped Renault by 0.1% market share or 400 odd sales. German and French brands dominate here.

30 Lexus 1,100 0.2
Others 3,750 0.7%
Total 572,200 +4.5%
The big improvers were VW (+15.7%), Skoda (+24.9%), Nissan (+18.4%), Hyundai (+45.5%), Dacia (+36.8%) and Kia (+27.9%). Losers included both PSA brands, Fiat (-17%), Suzuki (-22.8%) and Mazda (-35.9%).
For a country this size, car sales are strong. They like nice cars too, for example seven McLaren supercars were sold in the few months of their being available.
My take: A buoyant market seemingly immune to the economic chaos around it.

Car Sales Belgium: 2011

Belgium is a small country that builds many cars. The industry has had to deal with several issues that has reduced the number of cars made there. 1) It doesn't have it's own industry so depends on overseas manufacturers staying there, for which it has no control over. 2) Small countries have less political clout, so a plant closure has less negativity. 3) It is a challenge for higher wage countries like Belgium to be competitive against those nations with lower wages.
Looking at car production figures below shows recent decline. Ford is pulling out also in 2014, moving production to Valencia, Spain.

The 1990's production was in the million area, but today about half that. The VW includes Audis in recent times, so the figure refers to VW Group. It has been a settled production in Belgium over the years, but economic times are tighter. Last year Opel, now Ford's departure is big for a little country.

Belgium Car Production By Make: 1995-2011

Belgians like their cars, although they couldn't afford as many as last year. 2011 was a record year as far as I can tell so 2012 was actually not bad. VW and the French brands have traditionally been strong here and the three German premium brands too. The latter trio are all in the top ten and each gained a position in ranking. Japanese and Korean brands are not overly popular it seems. Both Land Rover and Jaguar experienced strong growth in a weaker market.
The first two columns are ranking for 2011 and then 2012. The last column is increase or decrease over 2011.
