The original Bumblebee was a Cybertronian Hover Car. Then a VW Bug. Then a reformatted car by the name of Goldbug.
Don't know why people are upset he's not a 5th or 6th gen. He's not even supposed to be a Camaro.
Also, the Camaro in TF:1 was a skinned Pontiac Goat -- not the Concept
I loved the Transformers as a kid and I still enjoy them... But, let's try not to turn in to zealots here.. They were then and are now a marketing tool to sell product. Hasbro was great with that. Hell, it's why they killed off practically everyone in the real Transformers: The Movie. More new toys!
