Tom ,Glad you are O.K. and still in the game !
One 'interesting' option for a replacement car may be Copart.
https://www.copart.com/lot/44297146 will probably sell for less than $500.
They are a bit tricky to deal with but many here would coach you through their procedures.
Thanks for mentioning a repair facility that meets with your approval.I hope they realize how valuable your endorsement is !
