Help! the Minis on my street are breeding!

What do I do!? I got an F55s back in June. Around December a Blue F55 showed up on my street a few houses down. About a month ago a grey F56 appeared. Now just a few days ago a black F56 is now on my street!

Please send help, I think they might be planning a take over! My street is a fairly short street and they are everywhere!! :D
