Handsome looks, a strong reputation for quality and reasonably generous equipment levels help keep re-sale values high. You can expect the 6 to hold onto a higher proportion of its value than some of the bigger sellers like the Peugeot 407 and Renault Laguna. Fuel economy is pretty good across the range and insurance groups are competitive. The 2.2-litre diesel launched in 2009 does away with a cambelt, so will require less maintenance than the 2.0-litre that was used during 2008.

A total of 35kg has been saved over the last model, despite it being packed with more equipment. That’s good news for emissions – they have come down by around 13 per cent over the previous 6. That means that the 1.8-litre now emits around 162g/km, while the 2.0-litre is 168g/km – far more in keeping with other cars of this size and power. The 2.2-litre diesel available from 2009 is the same or better (depending on version) than the 2.0-litre diesel launched in 2008.

In 2010 mild engine tweaks reduced emissions (by 4.4% for petrols and 4.8% for diesels) and improved fuel consumptions (3.2% for petrols and 4.1% diesels).

There should be nothing to worry about here. The old Mazda6 proved itself to be one of the most reliable cars on the market – problems were few and far between. This version should build on that and there are no causes for concern.
