So sorry for your DH's trouble.
I bought a used car on 4/30 of this year. following the sudden death of my 10 y.o. car. DS found it online for me the night before. Called the dealership first thing in the morning to be sure it was still available before driving an hour to get there. Arrived as scheduled around noon. Was allowed an extensive test drive by myself, during which time I drove it to a friend's house to have him check it out.
Returned to the dealership to make the purchase. Asked to finance the least amount they would allow, then paid the difference by CC and personal check- certified not required.
Drove the car home around 3 or 4 p.m. Did the entire deal solo.
Complimented my salesman and the manager on my experience.
Your DH is more patient than I would have been. Unless the deal was mad good (which it may have been, end of month) I would have gone elsewhere.
