I think the question is what should be my loss of use and how do I determine the value?
We never want to look at the time and money we spend on our cars, setting up our cars, and consumables versus the amount of seat time. For many the joy is in both working on and driving their car. What's the average cost of an autocross run or a track session? If it was a business, it would be bankrupt. For me it would be more of a loss of enjoyment, not as much as rental reimbursement but including it in the number.
If I have a car I drive everyday and a second car I use for fun/weekend, recreation. One weekend at no fault to myself someone damages my recreation vehicle and I lose use of it for several weekends. True I don't need it everyday and would drive my other car while being repaired. But I miss out on my recreational use of that vehicle. Can I rent a comparable car, use it as such, and at what cost? Would they compensate me for the exotic rental and consumables? Could I decide to take cash in lieu of renting the exotic?
I think the amount equal to renting an equal car for the actual useage missed would be a fair amount.

Now the big question. What is my lose of enjoyment if I choose not to rent the replacement?
