I'm most probably in the minority on this one but as I've been reading more on the l405, I've realised that Range Rover change things slightly but I can't find anywhere to find out when these things took place.

For instance tpms became standard but from what date cars?. I was advised the other night that the car has been updated now so you can put the heated seat on with one touch but from when?
And Land Rover now list the combined mpg ( yes I know it's garbage) as more than 40 to the gallon yet even the newest cars on the LR site still show 37 and I'm sure there probably many more. So is there an easy reference out there. Kind answers only please

TPMS became law at some point “i think” So all UK new cars must have it...

Yes TMPS just went from being an option to being standard

With all the other little changes, they are generally grouped into Model Years - or half years - so I guess thats the place to start - not sure where there is a definitive source for that info though

I read that from July 15 the road tax on the 4.4SDV8 will be £290. £200 drop .
