The DPF on the newer engine is said to regenerate twice as quick and half as often. Read into that what you want. My previous model 2,0d Mazda6 is reliable. It's just getting oil changes between services when needed.

The horror stories happen after (often soon after) the car comes out of warranty. If you're buying new and, as RTJ says, change the oil frequently, you should have nothing to worry about.

If I were buying secondhand, I think I'd want to see proof of regular fixed-interval servicing rather than those variable schemes that allow 20,000+ miles between oil changes.
