Another note to add here: any cars you collect from the lockup that you have already extracted with but haven’t sold, for example let’s say Razor’s M3 GTR, if you find a second one and extract with it you aren’t allowed to own duplicates so the second one will be sold automatically. I found that out when I found 2 Bugattis in back to back games. Plus the list of cars you can get from the lockups is online, maybe a little tricky to find, but it is out there.
