I would agree about the RX8 build quality..... Totally crap! Soooooo many electrical faults too
I don't think faults with the zed are all that bad or expensive really. Overall build quality is good with little or no rattles and everything is easy to work on. Compare that with issues with Porsche 996 non turbo engines and any Mercedes and it puts things in perspective I think.
Most common Zed issues I see:
1. window motors.
2. Bose HU
3. Gear Box
4. Soft top issues
5. C.V joints
6. Wheel bearings - fair wear and tear
