One mistake I noticed most people make they think early 70s and older vehicles will be okay but even those had a electronic ignition module that would be toast and there's a good chance it could kill the coil. Also someone else may know more about that than me but the older vehicles had a lot of fusible links on them and I'm not for sure if those would hold up or not.

I'm pretty sure the fusible links will be OK (gawd, I hated just the very idea of them in a car!).  For the short antennas (wiring) in a car the energy received won't be enough to get all those fuses red hot and melted.  The main problem is voltages can be high enough to zap semiconductors.  Especially this modern stuff where the supply voltages for most logic is 3.3V and some as low as 0.9V.  The oxide (glass) gates on the CMOS FETs punches through at less than 3x the supply voltage.  They put pretty good ESD protection on most pins, but still, it's crazy-fragile stuff.

Yeah some of these new electronics it doesn't take but one tiny little mistake, almost static electricity level, to cook something.
I sure don't miss fusible links though.
