Which used BMW 4 Series sports should I buy?
As mentioned earlier, the fact that the BMW 4 Series Convertible is so much heavier than the coupé means it is very tempting to stretch to a six-cylinder model if budget allows. However, for most it’ll be hard to ignore the lower purchase price and running costs of the 420d, even if it does mean settling for a car that is ultimately slower and noisier.
As far as trim levels go, you might save a bit of money by opting for an SE or Sport over an M Sport, but as they are relatively scarce and won’t hold onto their value as well, it’s probably a false economy.
In terms of equipment, all models come with everything you'd really need, including dual-zone climate control, BMW’s iDrive infotainment system, Bluetooth, parking sensors and leather seats. To this, M Sport adds sportier body styling, larger alloys and a firmer suspension set-up.
