To be able to do your own maintenance and diagnostic, here's a list of a MUST HAVE tools (metric):
1. Mity Vac
2. Craftsman (or better) mechanic's tool set (100 to 200 pieces) from Sears
3. Tourque wrenches 3/8 and 1/2
4. Fluid extractor 8 liters plus capacity (e.g., Oil Boy)
5. Floor jack and stands (2 sets)
6. Ramp
7. Special wrench for adjusting valves
8. A set of magnetic screw drivers
9.
10.
11.

and so on..

Your input is appreciated. At some point I will compile it and repost.

Thank you for time.
