The 3-Series Convertible is undoubtedly one of the most desirable models in the BMW line-up. It combines effortless elegance with everyday practicality and an exciting drive - in fact it is one of the finest drop-tops on sale today.

Running costs

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.
