Ten years ago I would have agreed with the OP's analysis (Several people did in identical threads at the time), but I can see the current crop of modern classics being caught out by green policy regulations already scheduled (in the UK).
They will not be old enough to achieve historic vehicle status and duck out of MOT, tax and emission zone regulations and will fall victim to punitive tax, fuel availability and other regulations limiting use, to the point that our older cherished cars become unusable static displays. It reminds me of the way large engined cars became unsalable in the 1970's petrol (price) crisis, but with no end in sight, just a future of electric conversions or being trailered to shows.
