My SIL had that problem, hard to find a rental and the repair company said it will be awhile before they can get the parts. If the insurance company totals his car, he is SOL.
Sis bought a new 4Runner last year and keeps getting several calls and emails a week from the dealer and other 3rd partys trying to buy it back. Offering more than she paid for it
They can’t sell or rent one if they ain’t got one
