BMW fans, hear this: A collection of seven M5s will go under the hammer at the Classic Car Auctions, on June 6th.

We don’t know what determined the private collector to get rid of all his prized possessions, but the man hoarded pristine examples of Bavarian perfection from nearly every era of BMW, over a 4-year period.

So, it comes as no surprise to see all of BMW’s “greatest hits” in the collection; beginning with the E28 and ending with the 25th anniversary edition E60. All these cars are pretty rare and carry the potential of being considered a future classic. This means the desirability of these automobiles will only go up, increasing their value over time.

Let’s kick off with the pair of E28s. The red example is an authentic M5 while the other one carries an M535i badge. The M535i was just a sportier variant of the regular 535i and didn’t have any BMW Motorsport parts. Still, it remains a sought after car thanks to its sports saloon role that kickstarted the BMW saloon dynasty.

The M5 on the other hand, is a beast. At the time of launch, it was the fastest saloon in the world. No wonder, since under the hood lies the M88 engine – a 3.5-litre, 24-valve DOHC inline-six – taken from the M1 supercar. A pure racing power-plant with individual throttle bodies and intake trumpets, which boasted 282 HP. The car was hand built, in Germany; it had the aerodynamics properties of a brick and the U.S version only had 256 HP. Nonetheless, the M5 E28 is one of the rarest modern BMWs. The example on sale has 283,245 Km (176,000 miles) on the odometer, but that’s not much for a well maintained car.

Next up is a pair of E34s sedans and a Touring. The E34 M5 was also hand-built, like the E28 before it, making it even more attractive in the eyes of collectors. The Touring model carries the same layout as any other E34 M-badged vehicle, but the body style makes it the rarest of the bunch – only 891 estate variants were built. The 3.8-litre inline-six, which develops 335 horses, powers the Touring and the black cars on sale. The Macao blue metallic example, with the 17-inch turbine rims, is powered by the 3.6-litre engine, which produces 311 horses.

The E39 is becoming a modern classic. The last of the classic BMWs received a 4.9-liter V8 along with the M5 badge. Unlike the previous generation of power hungry machines, the E39 was built on the same assembly line as the regular 5 Series. That doesn’t dilute its essence, though. Not by a long-shot. It still boasts 394 HP and had an aluminum suspension all around. The example on sale is a pre-facelift model. We’ve seen many M5s E39, but too few with the Imola Red color.

The star of the collection is the E60 M5 25th anniversary. Like the name states, this limited edition jumbo-Bimmer celebrates 25 years of M5 existence. It’s one of just 25 examples and comes in a unique Frozen Silver Metallic paint job. Even though this is an ultra-rare version of the M5 E60, it still comes with the standard power output. Nonetheless, the 5.0-litre V10 inspired from Formula 1 still has a word in the motoring world. 500 HP from a naturally aspirated 10 cylinder? Yes, please.

Besides the E60 with an estimated sale price of £25,000 – £28,000 ($38,225 – $42,812), all other Bimmers are offered at no reserve.
