So while we're on drivers, moving from screwdrivers to something else handy. A full set of flexible shaft nut drivers is a great thing to have. Really one only needs a few sizes - the couple for hose clamps, along with 8mm and 10mm. On BMW's we have a lot of 10mm hardware floating around, and I find the 10mm flexible nut driver super convenient for taking stuff apart and putting it together. Rather than a ratchet with extension and sock, of course. Once you use the 8mm and 10mm you will wonder where they were all your life. And if you are using a screwdriver or ratchet for your hose clamps, tsk tsk. These flex drivers tend to collapse at about 6 ft-lbs or so, which is perfect for a hose clamp.
I have a full set of these, a mix of both Stahlwille and Wurth. But honestly today I think the best deal is the Wiha 7-piece set one can purchase for about $125. If you want to save money, there are two ways to go - the first is just buy the common sizes you would use in the engine compartment, rather than the 7-piece set. The other option is to consider the KCT Auto Tools set for ~$60 shipped, though I am not recommending them as I have no direct experience with the set.
