What am I missing?

[Lost Boy]

I am just about to tax my new to me 2023 Ocean 204 4 Motion, I was expecting it to be £600 for 12 months, its coming up as £345 for 12 months, can someone tell me that £600 is the right number?

Thanks DGB99, so its correct....struggling to see how at 161g/km and then the supplement for over £40k it can be right, I'm not complaining I just wanted to make sure it is correct... seems weird as the internet seems to suggest it should be £600

managed to work it out, not taxed as a car but as a Motorhome...!
