I saw in another thread someone mentioning about tools.

From having had so many Honda vehicles (what 13 now??) here is what you need:

8, 10, 12, 14, 17, 19mm wrenches and sockets. You could also need a large 32mm socket if you are going to be changing drive-shafts.

90% of the bolts/nuts are 10, 12, 14, or 17mm.

It is good to have an assortment of sockets, 3/8" and 1/2", standard and deep. Get 6-sized (vs. 12-sided,) if you can for better grip.

If you have a Sport model, and want to adjust your fog lamp aim, it helps to have a 6" (or longer) #2 phillips-head screwdriver.

 

Having a Porsche which is pretty much all metric, having the tools recommended will be great, as I'll have dual uses for them. Not that I expect to have to do much to/on the Fit.

 

The 12 point 10mm and 17mm sockets are typically needed on Hondas when removing the pressure plate and flywheel.
