Turning 20. Anything to improve?

My TDF Blue on tan manual 575 turns 20 years old this year. She was specced with FHP, Daytonas and a blue leather rear shelf, sadly not 19 inch wheels. Maintained meticulously, she is magnificent to drive, be in and look at and listen to - the first owner fitted Tubi 575 back boxes which I kept on.

In most of my previous cars, 20 years and over 30k miles would have signalled to me, time for a suspension refresh, regardless of if anything actually felt wrong. My car drives extremely well, but of course I have no baseline of a new 575 with FHP to know whether say there's something faintly wearing out on shocks, springs, mounts, bushings, etc and I am no mechanic.

to be clear, I don't want to upgrade the drive on the 575, just want it to be as good as it should be. And then there's the question, if I'm going to replace x, should I use parts made by y, which are better than OEM, which then leads into upgrading unintentionally...

Should I be looking at replacing steering parts/shocks/anything else even if nothing seems wrong, just because age? If so, with what? If not, when?

 

Thanks folks, and the drink and meal is a great idea :-]

But while having minimal mechanical knowledge I still understand that mechanical parts are not binary, ie either working perfectly or not at all, like a switch. They're more like my own mechanical parts, slowly becoming less efficient with age, with increased friction between surfaces, more brittle elastic components, degraded elastic spring rates , fluids lost or losing their required physical properties, etc, meaning that a 20 year old high performance car with 30k miles is notably worse at being high performance than a one year old same car with 5k miles (say).

Like a lobster being boiled, the driver is not aware of this change in properties, but it has to be real. I know that Ferrari's media division requires a large number of steering and suspension components to be swapped out for new on all their press cars when they are decommissioned, for example, yet they all drive just fine, and they don't do this for no reason. And a 10k miles car has much more value than a 100k miles car for the same reason.

But I don't know what components are relatively robust and less affected by age and miles, and which ones have noticeably degraded performance over time and mileage, specifically in a Maranello, and that was the basis of my question - not whether my car will still be great to drive when it has 100k miles, which I am sure it will be.

I guess it may be a hard one to answer, which I completely understand.
