This supercharged 2006 BMW M3 Coupe sold for $31,000, and that’s strong money for a modified example with some serious upgrades.

Let’s break down what makes this M3 special. The 2006 model boasts the highly sought-after Competition Package, which enhances handling and performance. The 3.2-liter inline-six engine is further boosted by an HKS supercharger, elevating the driving experience to a whole new level. Coupled with a six-speed manual transmission, this setup is a treat for driving purists. The car is rear-wheel drive and features a limited-slip differential, which amps up the fun factor on twisty roads. The Jet Black exterior and matching Nappa leather upholstery add a layer of sophistication to its sporty demeanor. With 123,000 miles on the clock, it’s not exactly low mileage, but the damage-free Carfax report signals that this M3 has been well cared for.

Given the mileage and modifications, the price aligns well with market expectations for a modified E46 M3. While we don’t have a specific fair value estimate to anchor against, the bidding frenzy suggests that buyers recognize the value in a well-maintained, modified car like this.

Additionally, always check for maintenance records and ensure that the car has been serviced regularly. This M3 is a reminder that with the right modifications and care, a higher mileage car can still command strong prices in today’s market.
