Way way back, you could add the Supercharging option to S60s and S85s for $2000. It was 'included' in P85s and P85+ (but the price reflected the additional $2000). But that was when the program just started and they needed to raise funds to pay for the SC network build out. The cost to build out SC stations has fallen, and it's now included on (almost) every car, so at most it's worth at most maybe $1000, which is likely still built into the price of each car.
This is not correct. It was a $2k option on the original S60, but it was always included on all 85s.
