Maximum of 50 Cars?

So,

I don't know if it is just a bug or I am having a corrupted save but as soon as I reloaded my game after buying the 51st Car I was unable to join any game. Solo is playable (it seems), but I am only having my starter car unmodded and with a completely different character. I am not able to continue playing the game as I used to. Is there a hard cap to the max amount of cars you are able to have? Seems like its 50.

If anybody else had a similar problem or has an answer to this just leave a comment. THX.
