More cars have been spotted on the Transformers 4 set in Michigan. They are not in the movie for a fact, but they were seen around the set earlier today and would seem very out of place anywhere else. The group included a white Ferrari 458 Italia, a darkish colored Buick Velite convertible concept, a silver Cadillac Cien, and a blue Aston Martin Vanquish. These could all be Transformers, they could all be set pieces, or they could be a mixture of both. As a small side note, Bumblebee was also spotted on-set.
