Used BMW M5 Buying Guide: Everything You Need to Know
Looking for a high-performance saloon that doesn't compromise on practicality? The BMW M5 might be exactly what you need. Born from BMW Motorsport in 1979, the M5 has evolved from a niche performance car into one of the most celebrated super saloons on the market.
What makes the M5 special is its dual personality. During the week, it's a refined executive saloon with leather seats, plenty of boot space, and all the creature comforts you'd expect. Come the weekend, it transforms into a track-ready monster with enough power to rival dedicated sports cars. This rare combination explains why the M5 has maintained such a devoted following across six generations.
Whether you're considering a used M5 as your daily driver or weekend toy (or both), this guide will help you navigate the different generations, understand what to look for, and make an informed decision. Let's explore what makes the M5 such a compelling choice in the used car market.
Why Buy a Used BMW M5?
The M5 sits in a sweet spot that few cars can match. You get supercar-level performance wrapped in a practical four-door package. That means you can drop the kids at school in the morning, attend business meetings in comfort, and still enjoy thrilling acceleration when the opportunity arises.
Buying used opens up even more advantages. Depreciation hits hardest in the first few years, so you can access premium features and incredible performance at a fraction of the original cost. A three-year-old M5 might cost half what it did new, yet it still delivers the same exhilarating driving experience.
The M5's reputation for build quality means used examples often remain in excellent condition. BMW's engineering ensures these cars can handle high performance over many years when properly maintained. Plus, the enthusiast community means finding parts, advice, and specialist mechanics is straightforward.
For families who refuse to sacrifice driving enjoyment, the M5 offers genuine five-seat accommodation and a 530-litre boot. It's one of the few cars where you won't need to choose between practicality and performance.
BMW M5 Overview
The M5 story began in 1979 when BMW Motorsport took the standard 5 Series and transformed it into something extraordinary. That first model, the 535i, had just 1,650 units produced in its debut year. It established a formula that BMW has refined across six generations: take their executive saloon, add massive power, upgrade the chassis, and create a car that defies categorisation.
Throughout its evolution, the M5 has consistently featured powerful petrol engines paired with sophisticated transmission options. Early models offered manual gearboxes for driving purists, while modern versions come with lightning-fast automatic transmissions that deliver seamless gear changes.
Design-wise, the M5 maintains a relatively understated appearance compared to some rivals. Yes, there are visual cues like larger air intakes, quad exhausts, and subtle badges, but you won't find garish wings or outrageous body kits. This discretion appeals to buyers who want serious performance without drawing too much attention.
Inside, you'll find premium materials, supportive seats, and technology that keeps pace with the times. Recent models feature dual 12.3-inch screens, wireless smartphone connectivity, and driver assistance systems. The cabin strikes a balance between sporty intent and executive comfort.
Different Generations of the BMW M5
Sixth Generation (2011-2016)
When the F90 M5 arrived, BMW made significant changes to handle even more power. The mechanical platform received substantial upgrades, while the exterior styling took inspiration from the standard 5 Series with some performance-focused tweaks. Narrower headlights with laser technology, a lower and wider grille, and bigger side scoops gave visual hints to the car's capabilities.
The 2018 model year brought a game-changing xDrive all-wheel drive system, improving handling and traction. Previously, the M5 had been exclusively rear-wheel drive, but this new system could send power to all four wheels when needed whilst maintaining the car's sporting character.
BMW refreshed the model in 2020 with styling updates through the Competition Package. Black accents around the grille and redesigned LED taillights freshened the look. Engineers even improved the exhaust note by using thinner walls on the twin tailpipes, creating a more dramatic soundtrack.
The ultimate expression arrived in 2021 with the CS version. This range-topper featured sport bucket seats, carbon-fibre paddle shifters, and a comprehensive digital display. Weight reductions and power increases made it the most focused M5 yet.
Engine and Performance
Most recent variants feature a 4.4-litre TwinPower turbocharged eight-cylinder engine producing 616bhp. That's enough to launch the car from 0-60mph in just 3.2 seconds—supercar territory in a four-door saloon. The upgraded M5 CS version pushes output to 626bhp, dropping the 0-60mph time to an astonishing 2.9 seconds.
Earlier fifth-generation models used a naturally aspirated V10 engine producing 499bhp, whilst the fourth generation featured a V8 with 552bhp. Each generation brought improvements in both power delivery and efficiency.
Fuel economy has improved over the years despite performance increases. Recent models achieve between 25.2 and 25.7mpg, which is respectable given the performance on offer. Real-world economy will vary based on driving style, but the M5 manages to be surprisingly efficient during motorway cruising.
Practicality: The M5's Secret Weapon
Interior Space
Step inside and you'll find a cabin that prioritises comfort without sacrificing sporting character. Leather upholstery comes as standard, immediately establishing a premium atmosphere. The front seats offer excellent support during spirited driving whilst remaining comfortable for long journeys.
Rear passengers aren't an afterthought. Two adults fit comfortably on the back bench, with generous headroom and legroom. The middle seat works perfectly for children or smaller adults on shorter trips. ISOFIX anchor points in the outer rear seats make fitting child seats straightforward, highlighting the M5's family-friendly credentials.
Boot Space
The 530-litre boot easily accommodates several suitcases, making the M5 suitable for family holidays or business trips. The 40:20:40 split folding rear seats create even more loading capacity when needed. You can carry longer items whilst still accommodating rear passengers.
An electrically opening boot lid adds convenience. Simply press the button on your remote key and the boot opens automatically—helpful when your hands are full of shopping bags or luggage.
Safety and Technology
The M5 takes safety seriously. Euro NCAP awarded the 2017 5 Series a five-star rating, with impressive scores across the board: 91% for adult occupant protection, 85% for child occupants, and 81% for pedestrian safety. These ratings demonstrate BMW's commitment to protecting everyone.
Standard safety equipment includes multiple airbags, lane keep assist, and adaptive cruise control. These systems work quietly in the background, only intervening when necessary to help prevent accidents.
Modern M5 models feature dual 12.3-inch screens. One serves as an intuitive infotainment touchscreen whilst the other provides driver information. The system supports wireless Apple CarPlay and Android Auto, making smartphone integration effortless. A wireless charging pad up front keeps devices topped up without cable clutter.
What to Look for When Buying a Used BMW M5
Finding the right used M5 requires careful inspection. Here's what deserves your attention:
Service History: A comprehensive service history is non-negotiable. The M5's high-performance engine needs regular maintenance. Look for evidence of annual services and ensure major service intervals have been completed on time.
Known Issues: Research common problems for the specific generation you're considering. Some models have known issues with certain components. Understanding these beforehand helps you know what to check.
Test Drive: Don't skip the test drive. Listen for unusual noises from the engine or transmission. Check that all gears engage smoothly. Test the brakes thoroughly—they work hard in an M5 and may need attention.
Tyres and Brakes: Inspect tyre condition and brake disc thickness. High-performance tyres and brake components are expensive to replace, so factor replacement costs into your budget if needed.
Electronics: Test every electronic feature. Check the infotainment system, climate control, seat adjustments, and driver assistance systems. Electronic issues can be costly to repair.
Body Condition: Look for signs of accident damage or poor repairs. Check panel gaps and paint consistency. Stone chips on the front bumper are common but significant damage might indicate harder use.
Interior Wear: Examine the seats, steering wheel, and gear selector for excessive wear. These items indicate how the car has been used and maintained.
