Found it impossible to get a relevant sorting order on collection, see no system at all in where each car is listed.
I tried using this to enter a Forzathon race with specific requirements.
Only way I found was to skip Car Collection and go to race and there Setup and then Race Setup and then Car Restrictions.
Then after that Select Car and a decent amount to choose from was there.
So if wanting to get a 1964 chevy as required the other day, I could filter down do then easily select by setting 1964 as year make min and max.
This is rather tedious going through all those menues to do this.
So in Car Collection before going to race, both filtering options and sorting orders would help a lot. Sometimes I look for cars with high points for level up tier, sometimes brand and model, sometimes price order what I can afford.
So doing that either buy or rent if not already owned in garage. Often a stock car and rental is required etc.
It need not be a 5 minute operation to get the car required for a race.
