Well, the bottom of my engine bay on my car has a panel that covers it and like 7 clips and a few philip head screws.
You got to remove those without breaking them, lower and put the belly pan a side while the front of the car is supported off the ground. You can drive it up on to some ramps or use jacks and jack stands.
I tend to need maintenance in the coldest part of the year and end up breaking a few of those fender clips. You can find them cheap by the bag on ebay from China of all places.
Yeah, other than that, everything is easy to service.
