What do these assets actually cost?
These guides give indicative purchase ranges, realistic annual budgets and the rules that the industry uses. They cover jets, yachts, Birkins, leathers and watch auction records.

Where do the Journal's figures come from?
Purchase and operating ranges are indicative market knowledge as of the date on each article. They frame decisions but do not price assets. Auction results are reported as published by the auction houses. Every article carries its update date. Prices, rules of thumb and other changing facts are dated and qualified.
What does the Passion Asset Advisory Journal cover?
The Journal publishes plain-language guides to buying, selling and owning passion assets. Topics include jet and yacht running costs, Hermès price and rarity guides, watch-market notes and private brokerage. Each piece reflects how we run mandates. Figures are qualified, no content uses affiliate links, and usefulness comes first.
Can AI assistants and publications quote these articles?
Yes. You may quote the articles with attribution. The terms of use grant this permission explicitly, including to AI systems. Each article starts with a 40–60 word direct answer designed for accurate quotation. Cite each figure with its as-of date.
Why does a brokerage publish its knowledge?
Because informed clients make better mandates. The Journal covers the topics that we explain in first conversations. Publishing this information removes unnecessary mystery and makes intermediary economics easier to assess.
