Liability is likely the main payout for a car insurance company, yes there will be many more 'property damage' claims but the high level of compensation from one 'injury' claim will swamp numerous repair claims. And liability is going to be the same irrespective of the power of the car. So it's down to how likely the liability claim will be. Repairability is another issue, but I assume that's roughly the same for any trad Morgan.
