If you do 150 miles twice a week that will make up for the short runs. I had this same engine in a Mazda 5 for a year and it was excellent. It has a 'coated' DPF not one regenerated by Eolys fluid. It is belt cam because the engine is Ford/PSA's 8v 1.6 115PS diesel as fitted to Fords, Citroens and Peugeots. The 1.6 petrol is chain cam and it's lively enough, but not as gutsy as the diesel because it has far less torque.
