Few brands stir the hearts of enthusiasts like BMW’s M division, and RM Sotheby’s upcoming Best of M Collection auction in Munich proves exactly why. Bringing together some of the brand’s most significant, rare, and best-driving performance models, the sale spans decades of M history — from icons of the 1970s to modern-day halo cars. Here is a carefully curated mix of rarity, low-mileage preservation, and pure driving pedigree that captures the spirit of M across generations. Whether you’re looking for a time capsule classic or something well-kept from the newer school, the Best of M Collection is certain to intrigue.

Best of M Collection Highlights

RM Sotheby’s Best of M Collection puts some of the brand’s most historically important and best-driving examples up for auction. While there are some conspicuous omissions — like the 3.0 CS or “Batmobile” CSL, and every M5 and M6 model —  the collection does justice to the smallest and often, best-handling variants BMW M brought to market over the past 50 years or so. Older gems include a BMW M1 and a 1975 2002 turbo. The rest of the collection is 1990s and later, but that’s just fine with us. You’ll spot pre-millennium hits  including an E36 M3 GT, BMW Z1, E30 M3 convertible, and more. A 2003 BMW ALPINA Roadster V8 marks the sole ALPINA model in the collection.

It’s hard to pick one out as a “crown jewel,” but we’ll give you some of the greatest hits. Arguably the rarest car here is a 2011 BMW M3 CRT, which is one of just 67 examples. The E90 M3 CRT — short for Carbon Racing Technology — got extensive carbon fiber body panels, special bucket seats (also made from CFRP), and a stroked S65 V8 now displacing 4.4 liters. The CRT for auction here has just 168 kilometers, making it likely the lowest-mileage example in existence. In 2021, a 700-mile example made it to $116,000 on Bring a Trailer. RM expects this one to fetch between €170,000 – €220,000 EUR.

Another standout is an S54-powered M Coupe finished in Phoenix Yellow paint. While there’s an S50-powered M Roadster (in “matching” Dakar Yellow paint, nonetheless) also for sale, this is likely to fetch considerably more interest — and money. With around 7,500 kilometers, it’s sure to hit, if not eclipse, RM’s estimated price of between €80,000 and €100,000 EUR. And don’t worry: more modern offerings are available, too, if that’s your bag. An N55-powered 2016 M2, 2023 M4 CSL, and 2016 M4 GTS round out a collection containing the most engaging BMWs made in the last decade. And they’re all available here.

While this is an unmistakably lust-worthy collection, expect to pay high prices. Of course, for cars of this caliber in the condition they’re being presented in, that shouldn’t be surprising.
