Just a thought. No doubt you've looked at this??

May get it for what you want to pay. Originally asked 19k.
I believe each Zed currently on Carpoint is true to value if not a little underpriced especially when you get into the 25k+ market as it would cost alot more to do to these cars what has already been done. The ones under 20k, may require a little bit of TLC, or as a project, some personalisation. ie. wheels & tyres, or paint, or engine work, or interior, or all of the above.
Either way, the ones under 20k will never be the same value as, for example, this:

The engine work alone would almost cover the difference, not to mention the paint work and then there is the suspension resto also. A set of wheels and tyres would almost finish it.
