Thanks for the info and confirming it's not related to the car limit then.
After some more digging, it seems like some of those cars can only be used in Lockdown and can't be used in Free Roam or PVP playlists. That's possibly why they are not showing up in the normal "My Rides" section.
Here is an excerpt from our blog article on Lockdowns. There is a lot of information in there, but you can find it under JACKED & IMPOUNDED RIDES.
"Any vehicles you Jack and successfully extract with will appear in your garage as ‘Jacked’ and (inversely to Impounded rides) will be available for you to use for 24 hours, before they are returned. Jacked rides can not be used in Free Roam & PVP."
So, when you do extract one of those cars, they are only useable for 24 hours in Lockdown mode and can be selected from the "My Rides" section while in the Lockdown menu, not the main menu.
HOT RIDES
Hot Rides are found in Lockups and (if successfully extracted) are awarded permanently to the player who extracted them. If you weren’t the first person to open a Lockup and claim a Hot Ride, don’t despair just yet! As long as it’s still in the session, you still have a chance to take out the player currently using it, Jacking it for yourself, and then extracting to keep it!
Hot Rides can be used across multiplayer (Lockdown, PVP and Free Roam) irrespective of whether they are impounded or not within the Lockdown mode.
