I encountered this same change about 9 months back and found a way to get ALMOST back to the older format that would let one select the make, model, from / to year range etc.
This current one is like you are going to Ebay motors rather than the collector car section,
You select dodge, select challenger, and all years pop up,
One then has to select each year manually which is quite cumbersome. the previous version allowed you to choose a year range like, from 1970 to 1974
I bookmarked the way in and found i am back to this new format . Anyone know a way around this ?
