Just some info on the origianal Bee from movie 1.
According to the story, there were two versions of Bumblebee built for filming. The first one was completed in 30 days and both done in less than 45 days. Fabrication was done at Saleen's 280,000 square foot facility in Troy, Michigan. Steve Minn, vehicle coordinator for the film, recommended Saleen because they had built the Cobras used in xXx.
GM looked to their inventory and found the current GTO was the closest to the concept Camaro in size. With data and some sections and wheelbase drawings from GM, Saleen began their fabrication. The two Pontiac GTOs came from GM's R&D fleet and Joe Miesak (Saleen) went to work.
The fiberglass bodies were cast using the same molds GM used to build the two concept cars.
The interior looks much like the concept Camaro because the dashboard shell covers the original GTO instrumentation and the seats and interior handles came directly from the GTO as well.
GM had a say in the paint work. Supplied by Valspar Automotive finishes, code PBC30 -- Sunrise Yellow, Bumblebees paint looks great!
They altered the original stripes planned by Saleen to more closely resemble the Rally stripes from the 1969 Camaro.
Personally I just think it is the original movie car modified to a new level
