No engine either by looks of it....the ride height and lack of exhaust under the wing.
Well spotted Jay - if memory serves me well they are delivered that way and the reason they are onboard the fleet is that the fleet owner had one as a 40th Birthday gift from his wife. For some odd USA import reason he could not drive it for a while so decided to display it complete with engine onboard one of the ships.
The rest is historic as they say - hopefully it is a good sales pitch/talking point for the brand.
