Auto Trader Ten Point Test rating: 85%
The 1-Series Convertible makes up BMW's entry-level range alongside the Coupe and hatch. Launched in 2008, the Convertible goes up against the Audi A3 Cabriolet, Audi TT and Alfa Spider. Unlike its rivals the Beemer is rear-wheel drive – offering more kudos for those seeking a traditional sportscar-orientated feel.

1. Looks
While the standard 1-Series looks fairly bland, the convertible isn't, with its sleek and aggressive lines. Roof up it looks like the Coupe, remove the roof and it looks even better.
9/10

2. Looks inside
BMW traditionally keeps interiors neutral; here it's no different. The front of the cabin consists of dark plastics with a nice feel; the 1-Series is a very classy place to sit.
8/10

3. Practicality
For a convertible, the 1-Series is impressive. It'll seat four adults fairly comfortably and with the roof up, the boot has a capacity of 305 litres, reducing to 260 litres roof down.
8/10

4. Ride and Handling
BMWs have a notoriously firm ride and the model we tested, thanks to the M Sport suspension was no different; go over a speed bump and you feel it. Steering is sharp with plenty of feel and you can turn the traction control for some tail-out action.
9/10

5. Performance
The 123d's 2-litre diesel engine develops 204bhp and 295lb/ft of pulling power to give 0-62mph in 7.5 seconds and a top speed of 143mph. There is so much torque that the 1-Series is effortless at overtaking.

6. Running Costs
The 123d will average a claimed 52.3mpg; we averaged 41.5mpg. CO2 emissions of 144g/km mean an annual road tax bill of £125.
8/10

7. Reliability
The 1-Series Convertible is a superbly built car with a range of award-winning engines, so there should be few concerns here.
9/10

8. Safety
No EuroNCAP test yet, but BMW has a good reputation for safety. There are six airbags, ESP and traction control and in the event of a roll, metal bars pop up from behind the back seats to provide protection.
8/10

9. Equipment
Standard equipment includes CD player with steering wheel controls, electric windows, on-board trip computer, air-conditioning and alarm and immobiliser.
7/10

10. X-Factor
The 1-Series Convertible is a well-proportioned, excellent handling car with a whole range of brilliant engines coupled with that aspirational badge on the bonnet. These factors all help contribute to a great hair-in-the-air experience.
