My SO's car is a Ford (pretty reliable actually) and the first fix-it we did needed torx bits. Ugh, go out and get a set of those... come back and start again. I look around and they are everywhere. It might deter some, but to us it was a waste of time and a F-you to those of us who can fix our piles.

Oh, and a special F-you to whomever designed the absolute useless (not making it up; it's a 4 inch hollow chunk or metal welded to the frame nothing bolts to, hides inside, or protects) protrusion blocking a wrench from the oil drain bolt. A pox on thee!
