What used BMW 4 Series sports will I get for my budget?
The market for BMW 4 Series Convertibles starts at about £12,000 to £13,000, which will buy you a car from 2014 or 2015 with close to 100,000 miles on the clock. Spend between £14,000 and £16,000 on good 2015 and 2016 models, or between £17,000 and £20,000 on clean post-facelift 2017 cars. You'll need around £20,000 to £25,000 for a 2018 car, and around £25,000 for a decent 2019 model.
Whatever engine you decide on, it’ll probably come in M Sport specification, which accounted for the vast majority of 4 Series Convertible sales. The other trim levels are SE, Modern, Sport and Luxury, although all but Sport were dropped over time.
Cars registered after the tax changes of April 2017 came into force will set you back a flat-rate fee, currently £150 a year, and those that cost over £40,000 new will also incur a luxury car tax, currently £325 a year.
When it comes to servicing, it’s worth looking for an example that was ordered with BMW’s five-year inclusive servicing package, which is transferable between owners. There are no fixed service intervals as such (the onboard computer will tell you when it’s required) but, as a guide, you’ll need to factor in a visit to the workshop once a year to keep things running smoothly.
