The build quality is very good. The interior is very good and I have driven 30,000 miles. The interior materials look and feel high quality but the fuel consumption is too high. In addition the cost of maintenance is too high. I have experienced no issues with the electronics. The performance, practicality, styling, reliability and comfort is very wonderful.

This car is not a joke. This car is not to be underrated. Behind and under the hood is a powerful 500 HP v8 engine. The car easily will go from zero to 60 mph in under 4 seconds. This is one of the fastest models in the BMW lineup. This is also one of the fastest cars in the world. This car is so powerful, that it can be dangerous if not driven with care and safety.

The BMW M4 seems destined to forever be the second-most-exciting model in the 4-series clan, having previously played second fiddle to the water-injected M4 GTS and now finding its position at the top of the range usurped by the fractionally faster, fractionally firmer M4 CS. While the regular M4 remains a hugely desirable performance car, its suitors will be forever gazing over its shoulder and trying to flirt with its sexier sister. But for anyone forced to make do with the regular M4, there is some compensation in the form of a mild facelift for the 2018 model year, bringing the M4 up to date with the rest of the 4-series lineup. This is a shot of Botox rather than the sort of work involving scaffolding—what BMW likes to describe as a “life-cycle impulse” and one that hasn’t brought any notable mechanical changes. It does, however, give a chance for the regular M4 to remind us of its still considerable appeal. Other spec tweaks include double stitching for the top of the dashboard and some new chrome interior trim, although the M4 can’t be ordered with the digital instrument package that’s now offered as an option on the standard 4-series. Overall, it's good quality.
