well to be honest it's neither one nor the other, it's not a 2a ambulance and it's not a range rover due to the modified wheelbase
it's a stretched chassis (possibly) wearing the panels of a 109" ambulance so at present it's an uncertain pile of spare parts that are waiting to be attached to each other
there's no idea of what fabrication is going to be needed or what the registration intention/possibilities is, a stretched range rover chassis will retain zero points so "legally" has lost it's identity, the 2a bodywork carries zero points so has no identity to start with
so the question is, how much do you want to pay for a pile of spares ??
