2020 BMW M4 Heritage Edition

For those of us who never seem to win anything, prepare yourselves for an irrational bout of unbridled envy. This superb example of the M4 Edition M Heritage was won by current owner, Mostyn, in February 2025 in exchange for a £13 (lucky for some) stake. This stunning prize was awarded by competition company Dream Car Giveaways to Mostyn who has used it lightly since.

With four previous keepers registered for the M4, Mostyn became the fifth and the M4 today has still only covered a trifling 18,105 miles to date. The M4 is standard Edition M Heritage specification (which is far from “standard,” of course) with only the carbon front splitter and boot lip spoiler being aftermarket additions. Only 75 of the worldwide production of 750 M4 Edition M Heritage were earmarked for the UK and this is one of those very cars. Finished in Laguna Seca Blue it is one of just 25 UK examples to be finished in this colour.

With a full service history, despite the miniscule mileage, and a new advisory free MoT, this M-car is ready to relish and enjoy immediately. 
 

In tribute to that now familiar tri-colour M logo, the Edition M Heritage was released only in Velvet Blue, Imola Red and Laguna Seca Blue. This example is presented in gleaming Laguna Seca Blue, surely the best of the trio. Of the 75 UK supplied examples of this special edition, only 25 were finished in Laguna Seca Blue making this a very rare M4 indeed. Other external differentiators of this run-out model are the BMW M colours decorative strip integrated into the carbon fibre roof panel and the 20-inch, 666M, forged alloy wheels in a grey finish.

The remainder of the external treatment is what you would usually expect from a first generation M4 which, thankfully, includes perfectly sensibly sized and shaped, matt black radiator grills gracing the very handsome “face” of the car. Very sensibly, the front end, rear 1/4 panel in front of the rear wheels and the top of the rear bumper where it meets the boot lid of this M4 has been fully protected with PPF (paint protection film) which has kept the usually prone areas free from the dreaded stone chips. It is noted, however, that the PPF is lifting in places and also contains some minor blemishes itself. This could easily be professionally reapplied to continue the valuable protection achieved to date.

Our team also note that some of the non-PPF areas may benefit from a machine polish to unlock the true potential of the vibrant blue paintwork.

The 20-inch forged 666M alloys look entirely appropriate to an M-car of this calibre and present in a kerb-rash free condition with no other blemishes noted. The open structure of the wheels allows sight of the M-inscribed, blue finished brake callipers acting against the ventilated disks. A matching and staggered set of high quality Michelin Pilot Sport 4S tyres are fitted. These are in 285/30 configuration at the rear and 265/30 at the front.
 

A number of unique Edition M Heritage features grace the cabin of this M4, too. Specifically these include the exclusive two tone sports seats with blue contrasting stitching. These also feature not just the usual M4 seat back lozenge but also unique “Edition M Heritage” embroidery to the integral headrests. Other unique limited edition features include a unique carbon fibre dashboard treatment and additional Edition M Heritage identifiers to the sill kick plates.

In this car the Silverstone Leather is finished in the contrasting hues of white and black. These impressive competition seats are deeply bolstered, electrically adjustable and three stage heated. The rear cabin is identically trimmed and surprisingly commodious given the coupe body configuration. The M4 is a mid-sized car and hence no mere 2+2, but rather a surprisingly practical four seater continent crosser. 

Naturally enough, this is an impressively equipped M-car, too. Equipment includes Heads Up Display, 360 degree surround view park assist, Harmon Kardon premium audio system, lane departure warning and BMW Professional Multimedia system with dash top widescreen. The M4 even boasts a surprisingly commodious and well-shaped boot, further enhancing its surprisingly practical qualities. This is finished in dark carpet and provides a home to warning triangle and “get you home” tyre repair paraphernalia. 

Given this car’s mileage and careful use to date, the condition of the interior appears excellent overall. Many parts of the interior are reported to be in an “as new” condition with only some minor scratches noted to the interior of the windscreen.
 

In many ways the S55B30 engine that features here is the star of the car. A high specification unit specially developed by the BMW M engineers, it was used for only a relatively short period to power the M3 and M4 cars of this period. The S55B30 is a 3.0 litre inline-6 engine that uses two mono-scroll turbochargers, one for each bank of three cylinders. The engine also features a closed-deck crankcase design, a twin-wire arc-sprayed coating on the cylinder bores, Grafal-coated aluminium alloy pistons, and Valvetronic variable valve lift technology. In this iteration it is mated to a 7-speed DCT automatic transmission which is noted for enabling a faster 0-60mph sprint than its manual brethren. 

Additional M4 mechanical enhancements include adaptive M-suspension and M-Servotronic steering system. This mechanical configuration is sufficient to give the M4 a 0-60mph time in the early 4 second range and a top speed electronically limited to 155mph.

Given this car’s incredibly modest mileage, empathetic use and diligent service history it is unsurprising to learn of the condition of the engine bay and underside. Both are pristine looking. The engine bay manages to hide most of the S55B30 under covers and shields. What can be see looks entirely original, clean and straight. The underside is dressed in a full set of covers in hard plastic, alloy and sound deadening mineral wool. This arrangement helps guide the airflow of the car, deaden road noise and protect vulnerable componentry. Once again, what can be seen looks commensurate with a sub-19,000 mile car from 2020. 
 

Actual, tangible paperwork is so last century, of course. To that end just the current V5 registration document and an original handbook constitute the non-digital elements of the archive. This M4 Edition M Heritage holds a current, advisory free MoT which is valid until February 2026.

The big dashboard mounted screen holds the remainder of the information that prospective buyers will find important. Not only are the historic service entries available here but so is a real time status check covering all key aspects of this advanced machine’s operation. The historic service information reads as follows:

17.06.2020 – 19 miles
03.07.2020 – 1,111 miles
04.10.2021 – 5,337 miles
20.02.2023 – 12,420 miles
24.10.2023 – 13,925 miles
17.06.2024 – 15,286 miles

The various live status checks are also all in the green, underscoring this M4’s excellent mechanical condition.
 

Almost by definition the BMW M-cars are invariably pretty special. The specialist team charged with turning out the marque’s most desired and exciting cars have a generation of sporting experience and excellence to fall back on. The M4 is no exception but what may come as a surprise, however, is how useable and, dare we say, practical it is. Yes it has a screaming 400bhp plus M derived engine under the bonnet, but it is equally at home on the school run. It is that “car for all seasons” demeanour that really sets the M4 apart from its direct competition.

This superb example is an absolute gem. Firstly it can be reduced down to a batch of just 25 M4 Edition M Heritage in this livery and factory UK specification. A one of 25 car hailing from 2020 is somewhat of a unicorn. Then there is the very light usage and diligent BMW service history to date to further guild this enticing lily. This incredible M4 special edition, run out model has clearly been very lucky for Mostyn, and it now offers you a chance to make your own luck and become this M-car’s next privileged owner.
