An automatic center punch is another great tool for vehicle shenanigans. When pressed against the glass, the glass quickly breaks. It requires minimal effort, isn't loud like a hammer or other blunt object, and is fairly cheap to purchase. A center punch is also concealable, being around the size of a small screwdriver.
Spark plugs are a great tool for breaking into vehicles (or breaking glass in general). The porcelain at the end, when thrown at car windows, shatters them. Spark plugs are fairly cheap, you can find them from around 3-5 dollars online.
