Cars looping on a track

hey all, got an issue im not sure how to tackle.

i need a whole bunch of cars to loop around a track along a specific path. whats the best method to do this?

can i use a spline? (also can splines connect into a loop?)

or would matinee be a more simple solution?

or would a node path of targets be a good idea?

thanks in advance

Splines are the best, and yes splines can loop.
