I take it rear quarter has been painted badly ? Was car accident damaged ?
Clutch tends to ride high on zeds but may be on way out, was it slipping.on test ? Clutch on my first zed was replaced at 29,000 but on current one is still going strong at 46,000.
If the car is not a cat C/D price sounds about right but if it don't feel right walk away.
Tbh you are searching at bottom end of market and maybe you are being a bit picky but its a buyer's market at the moment so you can afford to be. At the money you are spending might be best looking for a JDM, you will get more bang for your buck.
