After test driving Range Rover and RRS I have decided to order The Range Rover - or I have tried to order one

Currently dealer has no up tp date brochures for yr14.50 model and you can't currently build one online. Which means I need to wait until configurator has been updated - but dealer doesn't know when this will happen.

So this means I still have not decided between Vogue, SE or Autobiography.

Let's look at this positively: This is a lovely problem to have!

Your dealer should be able to advise if there are any major specification changes between the previous and current model year, but ultimately it comes down to how much are you prepared to pay. If you go for a Vogue you may always be having that nagging doubt that you should have gone for a VSE.

If it were me, I'd go for the VSE. Discovery 4 HSE

Why not the AB

Because it's a King's ransom? Discovery 4 HSE

Going by the OP's question i don't think price bothers him

True Mick, but he is dithering between all three specs, typically people know whereabouts in the spec range they want to be, rather than just "I'll have the most expensive one".

I think the VSE has a great spec without being crazy crazy money.

However, if you can afford the AB, then clearly, it is the best one to go for. Discovery 4 HSE

Reason I cannot decide on spec is simply down to not been able to see what specs are for 14.5 models unless I am prepared to sit and look at dealers excel spec screen. If I am spending this amount of money I would like to see a brochure so I can come to a sensible choice between spec/options/price. Just surprised that LR does not have any upto date brochures or Configurator.

If you look at MY14 or 14.25 brochures the changes between these and MY14.5 will make no differences as to whether you choose V, VSE or AB.
