Honda Accord Subframe Rust-Out

I owned a 2000 Ford Windstar which I sold to my son. He subsequently sold the Windstar last November. Ford issued a recall on the Windstar for a rust problem involving the rear suspension. My son had the recall performed by the Ford dealer before he sold the vehicle. Ford Motor Company was buying back the severe cases, but the one my son owned was repairable. The Ford dealer had the van for more than a day.
I was really surprised the Ford would foot the bill on the repair of a 12 year old vehicle.
