My Agera RS unavailable?

I had the Agera RS, and since an update, it has become a DLC car. It’s now asking me to pay a single car add-on to get it??? I’m sure there are more of my cars that are like this, I will check and get back to this thread. I’ve already paid £25 quid(ish) into the game, WHAT DO YOU WANT FROM ME! This needs looking at urgently.

Just checked. About half of my DLC cars are unavailable.
