Two points that this is not exactly the subject. I refined it to look at "Good" desirable aircraft, for which players place New orders.
1. MD-80 no longer falls under "Good" in 2002. Things may work better for planes that are not good, nearly out of production, but my point here is that it does not work for planes that are Good and have new orders
2. The discussion is not about an actual purchase that one can make on UM, it is about the formula by which the system determines the "Recommended Price" around which the initial AI Broker Ask is centered. - of Good planes.
The used recommended market price is driven by player's actions, ultimately. Buy every A320 available on the UM, and you'll see used prices skyrocket. Forget 787s on the used market, and you'll see prices plunge. The link is not immediate, but it's strong, and consistent.
And also : define "good". Several players, including me, have been extremely successful in early Modern times playing the MD80 card, hence pushing pressure up on prices. Especially on used prices, we're not that many to order new. Who cares if it's old crap, as long as this old crap gives you a competitive advantage?
This is not about player sales, but the calculation the system uses to determine the Recommended Price for Used Market (AI Brokers, alliance sales, min max), and Dynamic pricing of New aircraft. Two AWS System level calculation that the system performs. They should match when the new aircraft is delivered on day 1, and instead, they show consistent mismatch. There could be a tiny mismatch that could be explained by "friction". But the current mismatch for A321 is $17m and that difference cannot be explained by friction.
Why?
Real life disagrees with you. A brand new car, direct from the manufacturer, standard common model, may cost 16,000€, and after 1 km, have a valuation of 13,000€. That's not unheard of. That's indeed the norm since 30 years in France. I don't know about Teslas, but given the difficulties to deliver from the manufacturer, I wouldn't be surprised if the used price would be indeed far above the "new" price.
It's not just friction, it's also 2 completely different markets. There is no reason to correlate those two markets. When everybody orders 787s new, and noone buys them used, the used price is crap, but the new price is high. When noones buys new MD80s anymore, but everyone jumps on used ones, used price becomes far higher than new one. Offer and demand. That's all. It works. It's fair. It's dangerous. It offers opportunities and dangers. One has to adapt.
