Locked cars in my garage?

I just got back into playing around with Forza 4 and I have some cars that I purchased or won and when I went to look. At them it says it is not available unless a buy the package!
That is totally not fair if I had it already it should still be for me to use. How can I get em back?

Try re-downloading the DLC they’re from. Not sure what else it might be.

They didn’t belong to a package when I got them but now they are.

I don’t know of any cars that were available but then became part of a DLC.

only cars that do that are dlc cars if the dlc has been removed, check your download history and see if you have forza dlc and re-download it
