The prestige of the BMW badge and quality of the product means that the 3 Series Convertible usually has some of the best residuals around. This should be further enhanced with the metal folding roof and sophisticated equipment (such as heat-reflective seats) on this latest car. Insurance and parts and servicing are expensive, but in line with other cars of this kind while the frugal diesels mean running one needn't be an expensive experience.

How much is it to insure?
Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
The 3 Series Convertible performs reasonably on the eco front and by far the best model is the 320d - this emits 140g/km of CO2 and is capable of 53mpg. Even the top of the range 335i isn't too bad - averaging 30mpg and emitting 226g/km of CO2, which is impressive considering it's superb performance.
Highest and lowest CO2 emissions
|Engine||CO2 emissions||Road tax (12 months)|
|320d Diesel||135 g/km (Min)||£145|
|335i Petrol||226 g/km (Max)||£555|

If a used 3 Series Convertible built between March 2007 and August 2011 is on your shortlist, then it’s important to verify with a BMW dealer that the remedial work has been undertaken.
