Try this and see if it works for you to sort by year.
Search for cars in your date range. Change the sort order to "Best Match". In the page address shown in your browser's address bar, somewhere, possibly at the end of the URL, you should see a parameter that looks like this:
&_sop=12
If you do not see such a term, try switching to a different sort order, and then switch back to "Best Match" -- that should ensure the term appears.
That is the parameter that controls the sort order. Use your cursor to highlight that 12 and change it to 22 instead, and then hit the "enter" key to load that page.
When I do that, it appears to sort the vehicles by year, starting oldest first.
If you want to see newest year first, change that number to 23.
Then bookmark or save your search so you do not need to edit the page address to see that sort.
