If your instrument cluster glass was broken, would you replace it with glass again, or plexiglass? (On the P15 it is just common clear glass, not curved or tinted, etc. The edges are not even 'dressed'.) Mine is not broken, but chipped a bit at the corners, and it doesn't come clean real well, so thinking of replacing it, either with plexiglass, or some better quality glass than what was in it.
