That applies to everything worthy of consideration once you're past 10 years old... Replacing an Omega with A ten year old barge will see the same issues beginning to appear and several others besides...
Looked at a 23 year old car last week... For example just opening the bonnet revealed missing covers, an oil leak that demands a HG change as the official cure and some future welding behind the headlights. A couple of minutes inside the car revealed an non working heater blower and mirror switch. Bare minimum in parts is £300 plus a couple of days work and another £60- £100 in tools. And that's before addressing the overdue service or any aircon issues that the lack of fan masks...
Even a tidy Omega can swallow a grand in bits and bobs just to get it mechanically straight.
The only reason to do bodywork on a 200k mile car is for sentimental reasons alone. That said, buy a tidy one and look after it and there's no reason why it won't do 300k.
The trouble is these types of car are 10-20 years too new to be genuine investments... So the choice you make is either preserve one for the future and run a daily driver to take the abuse (nice car or shed doesn't matter, but it isn't your weekend investment), or run a car you like as your personal investment, look after it and enjoy it but be content with the fact that you will never retire on its future value.
A nice well kept car is a nice well kept car regardless of make/model, age or mileage
