At Hitchin Autohaus, we’re proud to present this superb example of a 2006 BMW E46 M3 Convertible, finished in the ever-desirable Carbon Black Metallic over Black Nappa Leather. Built on the 3rd of August 2006, this late-production car features the iconic S54 3.2L straight-six engine, mated to the SMG II Drivelogic gearbox, offering rapid paddle-shifted gear changes and that addictive 8,000rpm redline — a true hallmark of BMW M’s golden era.

This car comes with a factory specification that will appeal to any genuine enthusiast. Highlights include the factory hardtop with prep, Navigation System Professional with TV function, Harman Kardon Hi-Fi, heated electric M sport seats, 19" forged Style 67 alloys, Park Distance Control, rain sensor with automatic headlights, Xenon lights, cruise control, and multi-function M leather steering wheel. Every box that mattered to an E46 buyer in-period has been ticked here.

Importantly, this M3 is backed by a comprehensive and continuous service history, tracing its life from new right up to 2025. The maintenance record reads as follows:

• 29/11/2023 @ 136,814 miles – Sytner BMW Stevenage

• 04/01/2025 @ 139,650 miles – VW Audi Specialists, Hitchin

The current mileage is approximately 139,700, and the car is MOT’d until March 2026, with a clean record and no advisories on the most recent test. The V5C shows just four previous keepers, with two of those being father and son — a key detail that speaks to long-term, family-based enthusiast ownership rather than high-churn hands.

Mechanically, this M3 performs exactly as it should — the SMG pump engages perfectly, the drivetrain is responsive and strong, and the steering retains that sharp, communicative E46 feel that has won over so many drivers. The suspension is composed, and the exhaust note remains pure and purposeful. The soft-top roof is in great condition, and the factory hardtop included in the sale adds genuine year-round usability and collectability.

This isn’t just an M3 — it’s a proper E46, prepared and presented for someone who truly understands what this car represents. It’s had the right maintenance, retains the right options, and it’s finished in the most timeless colour combination BMW offered. With the E46 M3 continuing to grow in status among collectors and purists alike, cars like this — with proper provenance, condition, and spec — are getting harder to find.

At Hitchin Autohaus, we’re a small, enthusiast-run dealership that lives and breathes the cars we sell. We’ve built our name on sourcing high-quality, driver-focused vehicles and standing behind them with transparency and pride. This M3 is exactly the type of car that defines our approach — a clean, honest, enthusiast-owned example of one of the greatest M cars ever built.
