BMW M4 Buying Guide: Cost, Reliability, and the Best Years to Buy

by Leo Wilkinson

The BMW M4 has existed as a nameplate since 2014 but it has plenty of back story, as the successor to a line of legendary performance cars stretching back to the first BMW M3 of 1986. BMW’s decision to rename the coupe and convertible versions of the 3 Series as the 4 Series from the sixth generation onwards saw the switch to an M4 badge for the high-performance variant, while the M3 continues in sedan and, more recently, M3 Touring wagon form.

Arriving a year or so after the standard 4 Series, the first-generation BMW M4 got the usual treatment by BMW’s famous M Division. That meant major chassis and bodywork changes, special alloy wheels and a bespoke—and hugely powerful—engine. While the previous M3 had switched to a V8, the M4 saw a return to an inline six-cylinder engine, although this time with a twin-turbo setup for a mighty 425 horsepower.

With a choice of six-speed manual transmission or seven-speed M-DCT (dual-clutch) transmission and rear-wheel drive (RWD) as standard, the M4 faithfully followed the ethos of previous high-performance BMWs. Some high-tech innovations and refinements were added but, at heart, the M4 is a brutally quick car aimed at enthusiastic drivers. As usual, some hardcore versions were added later in the model run, aimed at those after an even more visceral feel on the road or the racetrack.

The second-generation BMW M4 arrived in 2021. While it has the classic BMW M division makeover, the exterior—as with the equivalent 4 Series—is notable for its shift away from traditional BMW styling elements, and for its huge vertical twin kidney grilles. Power comes from an uprated twin-turbocharged 3.0-liter inline-six engine, with a choice of six-speed manual or conventional eight-speed automatic transmission. The big news this time round was the option of all-wheel drive (AWD) for the M4 Competition models that arrived later in 2021.

Our guide to the BMW M4 has the lowdown on which models you can buy, the best and worst versions, and how much you can expect to pay.

What are the worst BMW M4 years?

There are no major worries but, as with most cars, the earliest models in the BMW M4’s production run are those that seem most prone to subsequently corrected issues.

Is a used BMW M4 a good deal?

There are a few other coupes and convertibles that offer similar performance to the M4, but the BMW is hard to beat for its well-rounded dynamics and involving feel.

BMW M4 Generations

Second Generation (2021-present)

As with its 4 Series counterpart, any discussion about the merits of the new BMW M4 introduced in 2021 tend to revolve around its exterior design, specifically its huge, vertically oriented grille. That said, the grille and the latest version’s muscle-car-like profile are arguably better suited to the M4’s intrinsically brutish character. The usual “M” makeover includes wider bodywork, with extra air vents and tweaks inspired by BMW’s race cars. An optional "M carbon exterior package adds even more motorsport vibes, with additional carbon fiber reinforced plastic (CFRP) elements.

Looks aside, the latest M4 kicks off where the previous one left off, with power from a twin-turbocharged 3.0-liter inline six and a choice of two-door coupe or convertible body styles. The high-grade interior includes heated M sport seats and leather trim, while lighter M Carbon bucket seats are an optional extra. As you’d expect, it’s a much more high-tech interior than you’ll find in the first M4, with wireless support for Apple CarPlay and Android Auto, a 12.3-inch driver display and a 10.25-inch center display.

Power for the standard models is up by 48 to 473 horsepower, but torque remains the same as the first-generation’s 406 lb-ft. Competition models are punchier, with 503 horsepower and 479 lb-ft of torque, increases of 59 hp and 73 lb-ft respectively. While standard versions have a six-speed manual transmission, the BMW M4 Competition models have an eight-speed automatic transmission as standard. One major technical change is the availability of all-wheel drive for the first time for any M3 or M4 model. Branded M xDrive, it’s an option for M4 Competition models only. BMW’s Adaptive M Suspension—which allows you to choose between different settings for the electronically controlled dampers—is standard.

A (very) limited-edition M4 CSL was introduced in 2022, and features a boost in power to 543 horsepower, chassis mods and a weight reduction of 240 pounds, thanks partly to the removal of its rear seats. The M3 CS, another limited-edition model with a similar range of upgrades to the CSL and the same power output, was introduced in 2023. An update in early 2024 for the 2025 model year brought the M4 into line with other 4 Series models, with updated headlight and taillight lenses and the switch to “BMW Curved Display” for the dashboard, which combines a 12.3-inch driver display and a 14.9-inch center display to form one large screen that curves towards the driver. Other changes include new alloy wheel and steering wheel designs and a 20 horsepower boost for M4 Competition xDrive Coupe and Convertible models, taking them to 523 horsepower.

It’s early days, but the second-generation BMW M4 has a good reliability record so far, and owners haven’t raised any issues on carcomplaints.com. BMW was among the top 10 car brands in the 2024 Consumer Reports predicted reliability survey and has performed solidly in similar surveys in recent years.

The MSRP for the BMW M4 started at almost $72,000 when it went on sale in 2021. Now, the earliest used examples start from about $58,000 so it’s safe to say it’s holding its value very well. Later, high-spec models with lots of optional extras will set you back more than $100,000.

First Generation (2014-2020)

The name might have been new but the first-generation BMW M4 followed a familiar formula when it was introduced in 2014. As the high-performance version of the 4 Series it got the kind of cosmetic overhaul that BMW M models have received since the early noughties. Things like the lights, the door handles and the windows are carried over from the 4 Series, but the M4 has pumped-up bodywork, including wider front fenders and flared rear wheel arches, a rear spoiler and a bulging power dome on the hood. There are characteristic “twinstalk” door mirrors, while coupe versions have a roof made from carbon fiber to reduce weight and convertibles have the same folding metal roof as the 4 Series coupe. One thing to note is that there are only two-door body styles offered, so there’s no M4 version of the five-door 4 Series Gran Coupe.

Power comes from a twin-turbo 3.0-litre inline-six engine with 425 horsepower—11 horsepower more than the previous-generation M3, which had a naturally aspirated 4.0-litre V8. Maximum torque is 406 lb-ft—a 40% increase—but fuel consumption and emissions are about 25% lower. The gains are relative, of course, so don’t expect great mpg outright. All versions are rear-wheel drive and six-speed manual and seven-speed automatic transmissions are available. A range of motorsport-derived features provide the kind of sporty driving dynamics for which BMW M models are renowned.

As well as lightweight suspension and body parts to keep weight to a minimum there’s an “Active M Differential”—an electronically controlled limited-slip differential that shuffles the power delivery to improve traction. Early models even had a carbon fiber driveshaft, although this was later replaced by a narrower steel version in the interests of making space for a petrol particulate filter. Special “M compound” brakes are standard, but carbon ceramic brakes with gold-colored calipers were an option. Adaptive M Suspension—which gives the choice of Comfort, Sport and Sport+ modes—was another option.

While the basic interior architecture is shared with the 4 Series models, the M4 has a range of bespoke M Division features including M sport seats and an M-specific driver display, gear lever and steering wheel designs. Standard equipment is generous, as you’d hope of a car with an MSRP of more than $64,000 when new, and includes leather upholstery, climate control, LED headlights and 18-inch alloy wheels. In 2016, BMW added the M4 Competition Package as an option, offering 20-inch alloy wheels, an additional 19 horsepower, uprated springs, dampers and anti-roll bars, black chrome tail pipes and Shadow Line (high-gloss black) exterior trim details. A number of special-edition M4 models were also available.

The M4 GTS introduced in 2016 has 493 horsepower and a range of track-focused chassis and cosmetic tweaks, while the BMW M4 CS of 2017 sits between these, with 454 horsepower and a slightly less aggressive makeover than the M4 GTS. In addition to its lengthy name, the M4 Edition ///M Heritage Coupe of 2019 has all the features of the M4 Competition Package Coupe as well as bespoke 20-inch alloy wheels and special interior and exterior trim details.

The BMW M4 is a high-end performance car that generally has a good reliability record. As with any car of this type, however, it may have been driven hard or seen use on the racetrack, so check that the brakes, suspension and steering behave as they should on a test drive and look out for any aftermarket modifications.

Early BMW M4s for about $25,000 will be high-mileage examples. You may be better off spending a bit more for a lower-mileage car, because it’s more likely to get you better money at resale time. Another $6,000 should get one with less than 70,000 miles. M4 GTS models are scarce and command good money, so expect to pay $70,000 or more.
