It depends on too many factors to give you a straight answer. On some cars you can slip it out of gear without pushing in the clutch (can't on my Amigo though so I assume can't on your VX either). Considering how much I have to 'row' through traffic, I don't see how an extra shift now & then to take advantage of coasting will make an appreciable difference on clutch longevity. On a bad traffic day, I'd conservatively estimate that I push in the clutch 1000 times on my commute home. It also depends on your driving habits like how much you feather the clutch when shifting & stuff. Ideally each shift is done at a constant speed & acceleration/deceleration is done after the shift - that gives you the smoothest shift and will make your clutch last the longest.
