BMW 1 Series Convertible 118i SE 2dr

For For a reasonable premium over ES models, you get lots of extra kit, including rear parking sensors and a leather-trimmed, multifunction steering wheel. The engine is smooth and impressively frugal.

Against This is a lot to pay for a car with just with 141bhp and some of the cabin plastics are rather functional. Many rivals cost less and provide rear passengers with more space.

What Car? says

2 out of 5 stars

This is a desirable version of the 1 Series Convertible, thanks to its low running costs and generous standard kit. It's a little short on grunt and we think the ES version represents better value.

Buyer's notes

Target Price team says:

The 1 Series has a range of engines to suit every budget and taste. For us, the 120d supplies the best balance between pace and running costs and it's refined too. The smaller petrol engines are rather short on grunt, while the higher powered petrol and diesel models push the price too high.

Entry-level ES trim supplies all the basics, but stepping up to SE adds the kind of luxuries that many premium badge buyers will expect. M Sport adds a fetching bodykit, but it also has firmer suspension settings that make the ride less forgiving.

Running costs for the diesel models are low, thanks partly to BMW’s clever Efficient Dynamics measures, which helps towards stunning fuel economy and CO2 emissions.

Petrol versions are cleaner and more frugal than many rivals, but by any standards the 135i seems unnecessarily pricey. BMW offers three- or five-year fixed price servicing packages that can be sold on to future owners.
