Considering your car was parked and the other driver has admitted to causing the accident wouldn't your insurer go after his insurer to get your deductible and loss of use rental fee paid? Not sure how things work in Alberta, but in Ontario the other insurer would be responsible for paying your claim for loss of use (rental) and your deductible. You may wish to check with your insurer. Also, I believe you may be entitled to a rental vehicle of equal value if you were able to rent a Vette. Likely, no rental Vettes available in your area, but maybe a top of the line SUV and tell your body guy to take his time and fix it right. Cheers
If you don't have "loss of use" (rental) coverage and it sounds like SN3 doesn't (not the OP or original poster; he has it), the insurer in Alberta isn't obliged to try and collect your rental vehicle payment although some do as a courtesy. Insurers will however collect your deductible but most will waive that deductible when you're not at fault and the other driver has insurance. I assume that it works that way in Ontario. Having said all that, SN3 has ++ other vehicles to drive which explains him not paying for "loss of use" coverage since he can hop into another one when needed.
