I’ve just looked at the app and, rather unhelpfully, it doesn’t say what the subscription changes to when the Pro subscription expires on 2nd October.
If I click on the message that mentions the impending expiry, it gives me prices for Pro (£99) and Plus (£29) but nothing for Lite, which makes me think that it defaults to Lite, but I’ll only know for sure when the free Pro subscription expires in a few weeks time.
From memory, I think the car was classed as a 2025 model, as it was the facelift model which was launched last summer. The car certainly gets OTA updates.
