Same here. One of the reasons I didn't trade my MYSR for an MYP was when I had a chance last year.
I was actually able to prove that MYP would have more depreciation by getting quotes to buy it from various sites like Carvana, Vroom, etc. While the MYP has historically been $4,000 to $11,000 more expensive than the MYLR.. when getting quotes for the exact same vehicle and specs.. but changing from MYLR to MYP the buy offer was generally only $2,000 to $4,000 more.
And while this wasn't really a surprise, what is a surprise is just how many people have now purchased the MYP simply because it delivers several months faster than the MYLR. IMO the unexpected over-popularity of the MYP has pushed used price quotes even further down on the MYP down as most people do not want the heavy 21" wheels and expensive, skinny tires. Especially used. If both vehicles are available used then the MYLR is more likely to sell quicker and for more profit.. as its the most popular model with the longest range. All things that dealers are most interested in.
Hell even if I were to purchase a new MYP.. the first thing I would do is pull the 21" Ultraturbines off and replace them with lighter wheels and cheaper tires.
