Continuity mistake: When Bond's Mercedes is on the railroad tracks, it is hit head on by an oncoming train. As it is shown sailing in the air backwards, it is very clear that the drive-train has been removed. When the car is shown again, it is now sailing nose first as it hits the water.
Suggested correction: The drive-train hasn't been removed, it's just damage to the car from being hit by the larger and more powerful train. Surely a head-on crash would with a train wouldn't just leave a few scratches on the front of the car.
Look at pictures of cars hit at high speeds; the drivetrain does not just fall out, everything forward would have compacted towards the firewall of the car, and the rear differential is attached in many places on the chassis and certainly wouldn't have just disappeared.
