re: Is now a good time to buy a new truck in BR?

This will result in a shortage of used vehicles. We've seen this before in other flood areas. That's a lot of inventory removed from the market. You'll at least be in a good bargaining position with a re sellable trade in.

It's not good for dealers losing their new inventory. A total restock of new inventory takes a long time. They'd have to dealer trade/use locator services in the short term while they re stock from the factory.
