Should you buy one?

Yes, assuming you’re a discerning enthusiast that values rarity, fine engineering and stonking real-world performance. The B4 is genuinely usable day-to-day with good comfort given how capable and enjoyable it is in the bends and the option of making it feel much more special than a regular 4 Series Gran Coupe albeit for a hefty price.

Those that want a sharper experience are better served by the more aggressively set up BMW M3 and M4, while we suspect many will find the cheaper and more efficient BMW M440i Gran Coupe is quick enough.

What we like

The rapid acceleration is addictive and easily deployed thanks to the four-wheel drive system. Thankfully it’s more playful than the Audi RS5’s setup allowing you to have plenty of fun with a useful safety net. While the B4 is fun to drive, it’s still comfortable enough to be used every day.

It’s practical enough, too. The rear seats are big enough for adults and the boot’s a good size, while the interior is well finished especially if you opt for the extended leather packages.

What we don’t like

We could complain it’s significantly pricier than a BMW M440i Gran Coupe, but then the B4 is significantly quicker if a lot thirstier. Some may wish there was a coupe or convertible version, but that’s treading on the M4’s toes a bit too firmly.
