The easiest spammiest way to get this sepecific one is to park your Mako anywhere you can see it. Then, simply cast Neural Shock onto it.
You'll notice the red wave's of energy after you hit from each one casting, which means you successfully landed a hit.
It registers as an organic enemy being hit, just do this 75 times, no pressure whatsoever. The Mako will receive damage though so just in case repair it once or twice in the process to make sure nothing bad happens.
