I had a ford and when working on it I realized one thing:

This car was designed to assemble, not to disassemble.

Easiest example: the gray fabric-like panels in the trunk that cover everything? They are attached with small christmas-tree fasteners that mate with holes in the trunk walls. They take maybe 1/4 second to fasten. But to unfasten they take finesse to carefully remove without breaking the fastener.

Cars are like that all the way down. Also, a lot of these types of fasteners are designed to be replaced after you take them apart. But basically no mechanic does that. It's one reason why you have door and other interior panels making squeaking or other vibration noise after your car has been worked on.

Even decent reusable fasteners like screws frequently deserve a little locktite when replacing them and nobody does that.
