fuel economy and emissions

I have been offered at a very good price a 2001 Opel Zafira: low mileage. very clean, engine looks and sounds good and very dry, i.e. no sign of oil. No NCT, thouhg assured that with two new back tyres and a back window wiper it will pass.

My question is, how are these cars on petrol?

Is the automatic Volkswagen Sharan harder to run than the standard model. In diesel?

Wondering what the mpg is on a Chevrolet Captiva 2.0 LT VCDi AWD?

Nissan Note 1.5 petrol with automatic transmission: this vehicle is a Japanese import. Would the transmission make a difference to the car's economy?

What are the actual miles per gallon of the Skoda Octavia 1.0-litre?

What is the expected mpg of the Subaru Forester?

My 2006 BMW X3 is using more fuel than it should; what do I need to replace in order to stop that?

Thanks
