Two big holes (almost fist sized) near the front on the two rails going down the middle of the car. Small hole underneath the passenger floorboard. A little near the driver's rear wheelwell. I think the hangers for my exhaust broke off because of rust. There may be other small ones too. Other shit wrong is like brakes and suspension but that was gonna be replaced anyway... Hard to get a big project off the ground when you have these problems before you start.
