Bob,
I was contemplating having one fitted to the 90 - however any such change will have to wait until regular earnings hit the bank account again.
I have spoken to someone at CGON and all appears genuine. The only issue for me is lifespan of the device. If it gained approval to the extent of reducing vehicle tax that would be a big plus point. However, it would need to be greater than that applied to LPG/CNG conversions.
