swh: your poor grasp of the English language makes your post difficult to interpret at best.
Please explain; are you trying to tell us that the bloke who wants a brand new car should instead settle for something second hand because it will save money? Or will the second hand car have more features but cost more?
Your friend could have made the commercial decision to buy a second had aircraft that already has ADSB, TCAS, DFDR installed for several million dollars more, or a lower price one with the knowledge they need to comply with Australian requirements. It the choices one has to make when importing a 15-20 year old aircraft.
Please decipher .... I can't.
