I'm the front line supporter of aftersales quality as marketing issue. This is my profession anyway.

Concerning the topic, it may take years before Chinese will be able to built and estabilish the high quality aftersales support.

Even, when (if?) they purchase Linde Heavy Trucks Division, they won't take over the actual service network, which stays by the Linde dealers and usually is the part of their bussiness.

When we look at Koreans - Dossan is pretty strong in heavy trucks, the product is reliable and the prices are reasonable.
But they have problems with european market because of their lack of engagement here. They have some facility in Belgium but it's just a warehouse. The dealer network is rather weak (excluding UK, I presume), the technical and spares support is far from perfect.

As far as I know Doosan is aware of their aftersales weakness but IMHO this is the mentality problem. They still think - "sell and worry later", which is the basic attitude of majority of asian producers (excluding Japanese).
Remembering, that Doosan (Daewoo) sales trucks in Europe for over 25 years and still can't cross the line, I don't expect, that Chinese, will succeed here
Oops, sorry - Doosan few years ago purchased some micro factory, ATL in Germany, which makes some warehouse stuff.

Generally I don't expect, that Chinese, will succeed here.
Building the aftersales is not only the matter of the gang of servicemen cruising around.
It's the matter of culture and you shape it for years.
