1999: “I bought this 1999 Gmc sierra 1500 3 door truck about 4 months ago the body has no sign of rust.but underneath is life threatening I was driving normal speed maybe 55mph and I heard a pop and my frame broke in two different places because of rust. Now I welded it up just to get me back n forth to work. Witch is still life threatening but I have no other choice. I can not afford a new truck especially when I still got 3000 to pay on this one. The frame literally broke in half, under the cab on driver side, and by the back wheel on passenger side. …”
