I do the best I can with the model in the default scales of 1:24 and 1:25, and call it a day. Once I step up to a couple of 1:16 and 1:8 scale kits, I'll probably jam in as much detail as I'm capable of. Like many here who are getting older, the eyesight just isn't what it used to be, so I use magnifiers when and where needed, or just don't worry about it. Superdetailing chassis and engine compartments is not my thing at all, so that certainly saves me some grief.
