I have a friend who was in the same situation as you, he drives an expensive car and his commute suddenly went from 5 to 50 miles a day, 100 miles round trip.
I told him to go and lease a Prius, which he did for less than $200 pm. So there's another alternative.
By the way, in almost every case, if you sell a Car on consignment you have to leave it at the Dealership, it has to be there when a buyer wants to see it.
Good luck with the new job!!
