Of the 5 shops approved by my insurer in my city, the earliest availability I found was the middle of February. I could go ahead and use a non-approved site, but I would need to pay for the repairs upfront and then be reimbursed. I ain't playin that game.
There is a shop in a neighboring city (90mins away) that has a 3 week lead time but I chose not to go with them. I was worried that should there be a need for follow-up work after the repair, I would have to drive 3 hours (round trip), lose business days, and coordinate trans-city transportation on each occasion, as work is guaranteed by the repair facility and not by the insurer.
Since the other party was found to be 100% at fault, my rental is not costing me anything and I get to keep the car until I get the truck back. It hurts not having my truck while paying for it, but in the grand scheme of things......it could be a lot worse.
