i have seen that for pure rolling conditions,the point of contact has zero velocity and friction plays no roll in it, my concern is if all at a sudden the body gets a frictionless surface will it still maintain pure rolling or will start skidding, m taking rolling friction negligible and not taking into consideration.
Note that friction plays no role in pure rolling only if there is no linear or angular acceleration. I assume this is the case for your example. If so, pure rolling will continue over the ice. If there is no friction force on the rolling object, it will continue to rotate with a constant angular velocity, due to conservation of angular momentum. Therefore the contact point will remain instantaneously stationary relative to the ice. Do the following thought experiment: Gradually lift the object off the ice using a friction-less bearing at the center of the object, just a tiny bit, while it is rolling.

Kinetic friction doesn't play a role, no, but static friction can certainly have a say. There can be plenty of static friction in order to hold that contact point still.

It can continue the pure rolling motion, but only if the rolling very precisely follows the surface, so that the contact point still is constant. That would then be just a coincidence, since the slightest change in either rotational or linear motion would break the sync and cause the contact point to move relatively.
In the ideal case it will be the case if no other forces act horizontally on the car (no air resistance, no hills causing a tilting/non-vertical normal force etc.).
