That's my experience of going from a German car to a Honda. I can take the Honda apart with a screw driver and a 6-19 wrench set and very little else. I required one hex wrench when taking off the whole front of the car.
German cars tend to have a bunch of hex and star wrench requirements, in addition to specialized tools for certain parts.
On the other hand, older cars did mostly have way more space in the engine bay.
