The BMW Z4 (2006-2008) represents a transition in BMW's roadster lineage, blending classic styling with modern (for the time) tech. It's a desirable car for those wanting open-top thrills, especially in New Zealand with our fantastic driving roads. However, as with any car of this age, particularly a European one, prospective owners should be aware of some potential pitfalls.
Common issues include oil leaks (valve cover gasket, oil filter housing gasket), failing DISA valves (especially on the larger inline-sixes), and worn suspension components (control arm bushings, ball joints). The electric soft top mechanism can also be problematic. Check for error messages on the iDrive system (if equipped). The cooling system is another area of concern, so inspect for leaks and ensure proper operation of the cooling fan.
WOF tips
WOF failures are common due to worn suspension components (check lower control arm bushes carefully), brake condition (rotors, pads, flexible hoses), and headlight alignment. Rust can be an issue, particularly around the rear subframe mounting points and the underside of the car. Ensure the soft top latches securely and shows no signs of excessive wear or damage.

Key areas to inspect include the condition of the soft top, operation of the electrics, and the overall condition of the suspension components. Pay close attention to the oil filter housing gasket, a common leak point on the inline-six engines.
