NHTSA Complaint #11494659 — 2001 FORD RANGER

so I recently purchased this truck thinking it was all safe, the pictures were too good to be true thats for sure, When I brought the truck back the old owner even drove with me knowing what he just sold me. The next day I was so happy so I get it registered and insured and I was so eager to hope in and drive around in my new "safe" truck I also went out with my loved one and it sickens me that the old owner was ok with selling me a not so safe truck and I could have died if the frame bracket broke or the frame cracked while i was driving but when I started to look under I saw the problem and I was scared I saw that the upper control arm bracket mount was rusted and the strut tower as well it had a Hole forming and a crack on the strut tower. I also found out that there was a crack in the frame and i've looked up online and it seems that the frame and other components rust I don't know what to do. Im also a college student who is trying to get into the mechanic world and this scares me with how many trucks like this are out on the road.
