Smoothest diesel of them all?

What is the smoothest medium / large 4 year old (or less) second-hand diesel on the market today that emits 155 grammes of CO2 or less? I'm thinking of the Volvo S80 2.0, the Honda Accord CRDi and the BMW 520d.

Probably the Accord. A May 2008 2.2iCDTI EX is 145g/km and no DPF to worry about.
