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 31 - 47 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.

Residual values should be quite strong – certainly better than the hatchback, and all engines are capable of bettering 30mpg. Service intervals are long, but parts can be expensive. Insurance is okay.

307 is not particularly environmentally friendly. With an average of 188 g/km CO2 across the line-up, its emissions are fairly standard for a sports coupe cabriolet. The range is not particularly economical, averaging 37 mpg.

The 307 has not proven to be a very reliable car so far and although it feels well built, owners should expect niggly problems. Keep your fingers crossed that the roof doesn’t cause problems. A new electrical system in 2005 should improve reliability.
