Petrol or diesel?

My parents want to replace their ageing (2003) Mercedes C220 CDi. They cover 12,000 miles a year and are getting different opinions from every dealer over whether to buy a petrol or diesel. They're looking at BMW 3 Series Touring or Mercedes C Class Estate. Which would be the most suitable fuel choice?

If they regularly make very short runs from cold, less than 3 miles, then has to be petrol. If they regularly drive 10 miles or more, diesel fine.
