The tools in a factory tool kit are pretty minimal.
One person put it best. " ...the only useful tool is the screwdriver so you can stab yourself to death when you are stranded from a 914 break down "
I have assembled four tool kits with needed tools for common repairs.
Most are Heyco German made tools from BMW or Saab tool kits
