Not cars in particular but the Swiss and Austrians are obsessed with "Made In Switzerland/Austria" respectively. Especially for foodstuff (cheese, meat, etc).

I see this a lot less in Germany, maybe because nationalism in general is seen as somewhat in bad-taste here.

As someone from an EU country with no domestic caranufacturers: we don't care at all. We buy German. French, Japanese, Korean, Italian and even some US cars. Not many, see the Top Gear review of the F-150 to understand why.

My country does not have car manufacturers, but still supplies a lot of parts to car manufacturers around the world. My BMW was assembled in the US. Not in our neighboring Germany. The car manufacturing industry is much more geographically integrated than most people assume.

There have been occasional limp "Buy British" campaigns, but the UK car industry's reputation for poor quality kind of sank it in the 80s. I'm not sure how many buyers could tell you which Nissan/Ford/Vauxhall (Opel) models are made in the UK any more.
