I liked it. I really like the concept for showcasing cars as well.
The static pictures and the cuts went by a little too quick IMO I think if you lingered on the details like the engine bay, interior, etc a little longer it might give viewers a better taste of what the car looks like, inside and out. You could also do something like a slow walkaround with the video camera also.
I wasnt sure at first about putting the pictures in until I realized what you were trying to accomplish (if im not mistaken) of showing the whole package. With all moving shots its often hard to take a good look at the car, especially at speed. For this you could also try slowing the camera down as the car passes during one sceen to give people ample time to view the car, though it may present a resolution problem.
If you are going to supply a multitude of pictures and info outside of the video, then all of the above may not be needed.
This would be an amazing sales presentation to perspective buyers of a car. Supply a downloadable zip filled with various pics, info and a short video showing the car in action.
Maybe a quick information screen in the beginning would be nice too listing some vital info about the car featured like hp, engine size, etc. Nothing too lengthy, just the "meat" of the car.
I like 666fast's idea of being able to see the speedo or possibly the tach to show the car's true potential.
But I think its a great idea for, well, showcasing particular cars. I like the fact that the video is all about the car too. No music, no talking just the essentials. I think too many people get carried away with overly artistic shots and metaphors equating the car to some mythical beast or other such nonsense.
Anyway, enough of my incoherent babbling. Job well done!
