Thread: diff lock on RRS?

been test driving a couple of MY12-13 RRS 320's because SWMBO has decided to keep her D4V8. Not happy.

Did the locking rear diff even come as an option on the RRS's? all of them that I've seen don't have this as an option ..

I encountered the same difficulty when looking for a MY12 L322, giving up after 6 months and bought one without. However not to be beaten, retrofitted one 18 months later after spotting it in Estonia. The 4.4 TDV8 L322 uses a rare ratio so not many wrecks.
