2006 BMW Z4 M Roadster

Despite not having a roof, the Z4 M-Roadster managed to match the E46 M3 in terms of chassis stiffness. This makes for a capable canyon carver that can serve as a surprisingly good platform to build on. All with the added benefit of having unobstructed access to the high notes that come as the legendary S54 motor sings its song as it passes through 8K RPM. This example has had a list of the known issues addressed and appears to be in excellent condition, and it includes an upgraded exhaust to give it a louder voice.
