Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 33 - 56 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

It’ll hold its value better than other Meganes (but newer convertibles like the VW Eos and Vauxhall TwinTop are better still). There are good diesel options for those wanting to keep fuel costs down and insurance ratings are reasonable too.

The Megane scores well on the eco front. With an average of 171g/km CO2 across the model line-up, its emissions are quite low for a small family cabriolet. Eco-conscious buyers should consider the 1.5-litre diesel, which is one of the greenest models in the range. The range is also fairly economical, averaging 42 mpg.

These later cars seem to be better built and build was claimed to have been improved during the 2006 facelift. Some owners experienced problems with the roof leaking although the dealer ought to be able to remedy this.
