The BMW 3-Series Cabriolet has steadily gone upmarket over the years and is now become unaffordable for a number of buyers. The 1-Series Cabriolet is the answer to that: a drop-top BMW with all the glamour, but at a fraction of the price. But that's not to say it's cheap. Prices start at the £22,000 mark, which looks pricey when you consider that the larger Volkswagen Eos costs from around £20,000. But the 1-Series Convertible is a great all-round package - good to drive, refined and classy. An added bonus for buyers is that it even ticks a few boxes when it comes to being green and cost effective to run.
