Daily drivers "worth buying" ?

Grand caravans are the ticket. Mommies running the kids around usually drive them easy and do all maintenance. Nobody wants them so they are cheap. Add to that a little rocker rust that's easy to fix, cv joint noise or brake noise and they can be had for a song. I've always been able to get good gas mileage out of them and being able to carry 4x8 plywood is a bonus
