Chinese cars are unavailable in most of Europe. You can't buy one in France, nor Germany or Switzerland. 2 models are available in Italy, but at the Paris motor show earlier this month, there wasn't a single chinese car...
I have no info about Dongfeng being available in Switzerland nor Germany, or the UK. Is that with a private importer?
Only Brilliance was imported in Germany for a while, but some dealers have closed, maybe all of them, I'm not sure. Landwind has also stopped in Holland, and besides Italy where DR Motors has some success, Chinese cars are unavailable in Western Europe.
They don't sell cars, so a Suzuki dealership, you say. That's not enough to make a car available in one country.
What western-European customers expect is an importer at a national level, providing warranties and organizing distribution, with dealers in most big cities. No Chinese brand is offering that as of today in Western Europe.
Some dealers are trying to sell Chinese cars at a city-level, but it's very difficult (and it will get worse) without a importer at the national level (or European level).
The Chinese brand who has the most potential in Europe is Geely. With Volvo they have dealers, and I guess they will try to convince their dealers somehow to sell Geely cars also, most likely in separate stores.
