I would look for a TDI LIMITED if you can get one for the right money,thats what i am looking for at the moment.
I currently have a LWB 2.2 and the cooling system is not that good - I would go for a TDI ltd as they are better on fuel, and more economical. The 2.2 is not that good on fuel.
If you are going for a 2.2, look at the head gasket - check it has been done if over 60,000. Check for mayonaise on the oil filter cap.
