Hagerty values the 2006-10 BMW M5 at $36,000 in its 2026 Bull Market List. According to Hagerty’s own release, 58 percent of interest in this generation of M5 comes from enthusiasts under 40, an unusually young buyer pool for a European luxury sedan pushing two decades old. This is the E60-generation M5, the one built around a screaming ten-cylinder engine before BMW moved every subsequent M5 to a twin-turbo V8.

The V10 BMW Never Built Again

Hagerty’s release points out that “whereas most high-performance BMW M engines are related to regular-series motors, this 5.0-liter V-10 (codename S85) is a complete one-off.” BMW built the S85 with no other application in mind beyond making the M5 the fastest naturally aspirated sedan money could buy, and never repeated the formula.

Why Younger Buyers Are Driving This One

A sedan built around a race-derived V10 that revs to a redline most engines only dream of was always going to age into a cult object, and Hagerty’s data suggests that’s exactly what’s happening.

An Engine Complex Enough to Keep Supply Tight

The S85 V10 has a well-earned reputation for being expensive to maintain, which has largely weeded out neglected examples from the surviving pool.

The Bottom Line

You can still buy a genuinely great E60 M5 for $36,000. If you’ve wanted a V10 sedan that BMW will never build again, the case for buying sooner rather than later is sitting right there in Hagerty’s own numbers.
