Random hit location tables are good for determining exactly where someone gets injured when hit, and the concept can easily be extended to cover vehicles, buildings, and other things. Here are two examples:

Realistic vehicle hit location table (d8)
1 - Drive wheel / thruster (lose 50% of speed)
2 - Controls (vehicle cannot turn or stop)
3 - Manoeuvring wheel / surface (lose 50% of manoeuvrability)
4 - Fuel line (lose 25% of fuel)
5-8 - Chassis (no effect beyond cosmetic)

Cinematic vehicle hit location table (d8)
1 - Chassis (no effect beyond cosmetic)
2-8 - Fuel tank (vehicles explodes in huge fireball)
