Up the Creek without a Car

Hi guys. It is with great regret that we are coming to you with a plea for help. About a month or so ago, we lost our 2nd vehicle due to a vehicle hitting it while it was parked. We were on our way to saving for a replacement vehicle, when we got hit last week with a flooding kitchen sink, an emergency room trip for Dylan, and an emergency root canal for Gary. As luck would have it, insurance covered nothing for us. Well we were able to skid through that by the skin of our teeth, but on Sunday the truck's engine cut, and this morning we found out that it would cost more than we have to fix it, and that the repairs would out-value the car. 
As most of you know, Gary drives his personal car for his job delivering food for Mary Angela's, so as of today, and until we can gain a new vehicle, he is effectively out of a job, eliminating 35-40% of our income.
Additionally, I have multiple pre-existing conditions which put me at a high-risk for a poor outcome should I become exposed during this pandemic. Without a car, we have no way to avoid going in to stores for all of our needs, rather than taking advantage of curbside pick-up options.
We are out of any financing options right now, and simply have nowhere left to turn, other than the kindness of strangers.  We are only looking for enough money to cover a single, used car, that looks like it could run for a couple of years with little repair work, ASAP. Thank you all, we appreciate your time in reading this.
