The early S-Max models weren't fitted with DPFs, however I am not sure exactly when they started to fit them.

It's only a sample of 1, but my Mondeo IV 2.0 TDCI estate has had precisely one brake light bulb failure in over 2 years and 24K miles (cost of repair = £1.50). No DPF issues, and an average of 42.5 genuine mpg in that time. I'm very pleased with it, for a company car.

However I think I will be looking at an S-Max to replace it next year, the 7-seats-as-standard flexibility would be handy with all the dad's taxi runs I'm doing these days ...

As I've often said, some cars are more vulnerable to abuse than others, French cars in particular. But if properly looked after and driven, they can give good service. I had seven reliable Renaults in succession, three of which did over 100,000 miles each. I'm sure that applies to your Peugeots.

An S-Max will do you fine if you can get one that's got a full service history (easily proved) and been considerately driven (more difficult to prove but you have to make sure you're allowed a good long test drive). Generally an average mileage is a better bet than very high or very low.

Thanks for all the advice. We have looked at a Mazda 5, but both my wife and I thought it was too plasticy and too small inside. I agree a Verso will be reliable, but not sure I could bring myself to drive something that dull.

We actually test drove a 2006 E220 CDi Elegance estate last weekend; incredibly well made and 2 child seats in the boot, but it felt too slow and soft. The garage are looking for a 6 cylinder Avantgarde for me (which apparently has harder suspension), but I think it will be even more significantly out of budget.

At the moment the S-Max is still the front runner!
