"off road pack" - standard on 2017 wildtrak?

[gasket]

Hi everyone, first post in this area of the OC forum.

 

I'm waiting for the dealer-network to reopen and then I'm off to buy a used Ranger. I'm aiming for a 2017 model, most likely a 3.2 Wildtrak. But I'm having some difficulty tracking down information on the off road pack (locking rear diff and some underbody protection). I genuinely do use off road functionality as part of my work and the diff is a must (along with better tyres) - the ranger will be replacing a discovery.

 

But, I'm struggling to find out if this was fitted as standard to the Wildtrak or if it was still an option (the latter makes it difficult to find used models with this fitted).

 

Could anyone advise if it was fitted and if not if there is a quick way of checking remotely (eg a sticker or a vin code element)? Obviously, when I go to see the various contenders in person, I'll be crawling under so will be able to see.

Thank you.
