Some part of being male seems to draw many to what is sometimes called "complication"--hence the attraction to the analog vs the digital, more gauges vs less (such as some choosing to have both an ammeter and a voltmeter), etc.
I have a fuel/air gauge I took off one of my race cars which has a really neat LED/digital display that would tell me on a constant basis how close I was to the ideal mixture. I also have a vintage Heuer Monte Carlo 12 hour clock /stopwatch combo that would let me or a non-existant navigator know exactly how close we were to arriving at the next non-existant checkpoint on time
I think the dash of a 100, being an elegant copy of the car's profile, looks best when kept simple. The central console of the later cars invites drilling more holes and hanging more thingies. In the end the car belongs to its owner who is free to decorate/desecrate it as seen fit.
