As we have frequently seen in the past new-model aircraft take quite some time after initial lauch to reach their full potential. When parting with the sums of money involved in the procurement of such a machine then the prospective owner should be aware that the machine is quite likely to be plagued with problems: some minor, some not, for a number of years. I have been told that this was the case with the A119 Koala - and this was based on the proven A109.
If your client doesn't demand very high availability and has lots of money, then go for it. People need to buy the machine for it to have the opportunity to improve.
However, if the machine is to be a hardworking machine in daily use then I would be of the opinion that the same money should be spent on a proven machine of known reliability.
Good Luck
