No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.
Relative to the Earth, yes. And actually, neverminding the Earth's rotation, their velocities are still the same. The velocity of the Earth around the Sun, the Sun around the Milky Way and the Milky Way streaking out from a primordial universal "center" make the Earth's rotation - and indeed, the car's personal velocities, irrelevent. One could be going 100 kph and the other be dead on the road, and in a cosmic sense their velocities are identical. Only the energy each is expending differs in that scenario. Remember, running up and down the aisle of an airplane going 700 mph doesn't actually change your velocity. Just makes you tired!
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.

no it is not, velocity includes speed and direction and while the speeds are the same the direction is not

yes of course!
100 km and 75 km are displacements, NOT velocities. The resultant displacement is 25 km north,
3.00 m/s
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
Take a train going west at 100 miles per hour and another train going south at the same speed. Their velocities are different because velocity is a vector quantity that gives both speed and direction. Since they are going in different directions they have different velocities.

Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.

No. Velocity is described as a speed in a certain direction. Since they are in different directions, they are different velocities.
