Servicing is not cheap. Engines can be tricky to work on, so not one for the DIYer. Fuel economy is so-so because of the big body.

406 scores well on the eco front. With an average of 176 g/km CO2 across the line-up, its emissions are quite low for a medium-sized saloon. However, it’s worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

Eco-conscious buyers should consider the 2.0-litre diesel, which is one of the greenest models in the range. The range is also fairly economical, averaging 41 mpg.

An enviable reliability record so far – most have been maintained properly by fleet managers. The long-term outlook is looking good but time and mounting mileages will tell.
