From the 5th dec 2019 video: This is surprising me, tell me your thoughts. The white-silverish cars line. For sure used for testing, perhaps some for crash tests. They doesn't look to me as all M3 or MY, but i can be wrong. I see, starting from the upper white car, - 4 cars rounded aft window and a bulky rear. -Then follows what seems a bit crushed M3. Then follows 3 cars: - a silverish model exactly similar to the first 4. - a white model with a sloping rear and a sort of bi-tone bumper (or just a big black plate), that looks like a M3 Coupè - a black MY/3 for testing. For sure the last 3 cars are not the same car.
