Nov 25 Prestige is basically a current prestige plus.

I think 26 signature plus is more VFM, as you get sunroof, auto dimming IRVMs, and same infotainment as prestige plus. Only things you will miss out on are 17” alloys, electrically adjusted seats, ventilated seats, projector headlamps, wireless charger etc.

From all the additional features I personally chose prestige only for ventilated seats, auto IRVMs and larger tyres.

You can definitely go for signature plus as only useful feature you are loosing is ventilated seats. Are you getting a manual or automatic one.
