Yes quite possibly.
This is why I’ve got an attic of spares for my cars that I’ve bought ,new old stock,as and when they pop up on ebay over the years.rather than current new spares.!
Can’t beat older or original quality stuff over new pattern for majority of bits
This is precisely what I have done since the mid eighties with Triumph parts. Then I ran a 2000 as my every day car and liked it so much that I couldnt envisage myself selling it. I now have six of them including that one, and my large collection of original genuine parts that I bought for little money then are now hard to find and in some cases worth a small fortune. I have recently totally recommissioned two Triumphs that had been off the road for over 25 years and I needed to buy very few parts to do it. I often get contacted to see if I have parts by other Club members and if I have surplus, then I will sell them.; if not, I keep what I have for my own use.
I have also owned Omegas since 2004, and class them similarly to my Triumphs. I have 3 very good examples and can't see any need to sell them. I have accumulated many genuine and original VX service items and parts, some of which are now no longer available.
If correctly stored, then I have a good supply of original parts for my own use - if I never use them, then ultimately there will always be someone who wants genuine original parts, especially the unobtainable or NLS parts.
There are financial and storage factors that come into it, plus the intended period of ownership, but if this is doable, then I don't see any arguement for not doing so.
There is too much negativity in my opinion about how long Omegas will remain a viable car to own and run. If someone enjoys their car and maintains it well, doing as much preventative work as possible to keep corrosion at bay, then they may last a lot longer than some owners are giving them credit for.
If I had had the same negative outlook about my Triumphs in the 80's when there were lines of them in scrap yards and they were corroding away around you, then I wouldn't have had six good examples today.....
