I have a similar experience, but with purchasing new RTL's
2012 RTL purchased 7/2012 @ $26,499 - no trade-in
2014 RTL purchased (new) 3/2015 @ $24,715 - Trade-in 2012 @ $14,000 (20K miles - 2 yrs. old)
2022 RTL purchased (new) 4/2023 @ 26,497 - Trade-in 2014 @ $9,500 (60K miles - 8 yrs. old)
I didn't get much for the trade-ins but for new ones the price change isn't much seeing as the 2022 was $2 less than the 2012. 10 years little change, if you purchase a left-over.
I did a quick search and found new 2025 RTLs in the same ballpark as 2012 prices, from $24,997 to $26,499. Probably less in a few months,
