I assume that the point of their maintenance and repair comparison is to help consumers figure out the cost of owning the car. The target audience would be people comparing different cars to figure out what their overall costs might be for the different options. Such a consumer would be comparing typical maintenance and repair costs, fuel costs, insurance costs, license and registration costs, and probably others I am forgetting. If that's the case then I'd expect collision repairs to not be included in maintenance and repair costs, because collision repairs are usually handled by insurance. If a particular car is more expensive to repair after a collision that would show up in higher insurance rates and so when comparing cars is accounted for when your compare insurance costs.
