Murcielago question

I'm in the market for a manual Murci.

A proud owner of Dr. Pathmanathan's book 'Murcielago' but it is silent on the difference between models with the suspension settings next to the gear shift and those without.







Is this as simple as, those cars without didn't have the adjustable Koni suspension?

In which case, surely these are more desirable buys later down the line?

Does anyone know the model years this changed in?
