Residual values do not hold up well, but other costs are reasonable. Dealers often offer incentives like free servicing too.

45 performs well on the eco front. With an average of 169 g/km CO2 across the model 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 42 mpg.

No serious faults; proving reliable as long as the service history is adhered to.
