All you need to do is look at the Aeromax build record on this site (in the Special Information section) to see that repairing an Aeromax is not a simple task. In particular, the rear section and roof is one piece and as it is made of aluminium, it isn't simply a matter of panel beating. Even minor damage to an Aero 8 is costly to repair and therefore, even if the chassis isn't damaged (this hasn't been confirmed and buyer beware), the cost to take apart the Aeromax and put new panels in place may be too cost prohibitive.
For MMC to warn the dealers about Morgan Aeromax 38, the damage must be significant.
