Sure you were. You already found a single one and discussed it just above.
Let me quote your own link back to you: https://www.kbb.com/toyota/corolla/2005/
A Toyota Corolla MSRP'd for $14,220 in 2005.
We haven't even started discussing your 2025 list, I'm just criticizing that you used a "top 10" list as a source saying "there were only 10 vehicles that existed meeting this criteria".
Meanwhile, if you look at your other sources, the Pontiac Sunfire link you posted shows that one did MSRP just over $15k, despite it being on your "top 10" list.
You really are in no position to criticize other people for "no amount of data will change your position", when all the data that you have presented so far is some combination of misleading, incorrect, or hallucinated.
