Consumer Reports bought some cars with "salvage" title, and then took them apart.
What they found was shocking.
Cars cut in half, then welded to another half car...
Cars that had the roof cut off, (fire department rescue), then the roof and "A" pillars were replaced.
Terrible weld jobs...
Water infiltration under carpets, into electrical, everywhere. Rampant rust/corrosion starting after only a short time...
Do not walk away, run, as fast as you can...
