The car they get you should be a ever so slightly lowered stock Explorer

They're not THAT bad on gas when they're stock.
Can't believe someone got you like that.. That's so messed up.
The wiring isn't gonna be the worst thing ever, they didn't rip the ends off it looked like in the posts.
Make sure you're soldering, heat shrinking, and possibly even doing the 'silicone trick' when you connect these wires back together. Or whoever's doing it. You solder with the heatshrink on the wires you're joining, then before you heat-shrink the heatshrink, you dab some silicone (RTV probably would work I'd imagine,) and heatshrink it over the silicone to squeeze it out so it makes a weather proof seal. Never had a problem with it and many people can attest it is valid and safe!! Last thing you need is electrical ghosts because there's weird interference happening on the repaired wires. Not worth the headache
Anything someone can quickly slash can definitely be replaced! I really hope it gets sorted out quickly because it's a damn shame. I'd probably just die if someone did that to me.
Edit: you know, upon giving it some thought.. It may be easier to buy a parts 01 sport than it would be to source all of the parts individually for $$$ reasons. Depends on what your insurance company is having you do etc etc. Dunno can't really say much since I don't know a lot about your situation, but yeah, whatever you do, I hope it is easy and not a horrible experience upon another horrible experience. Nobody deserves that kind of thing on them
