A couple of reasons:
Apparently only LHD are available new...this came from a UK supplier in 2 days.
I was irritated during a drive last weekend that the indicator stalk was on the wrong side,
so this has fixed my frustration!
My old unit was a bit loose on the light stalk, but worked fine.
So, all in all, a nice to have upgrade, but not essential!
And yes, inspired by BOM!
