Is this put as a general car question or for a particular car, by you posting in this section, I'm assuming S2K/NSX....

On my own account, the standard speedo is normally on average off by +3kmh - +4kmh at speedo indication of 100km/h.. The difference is wider as the speed gets higher..

Any idea of how much the Yellow Box will cost when it's landed in Australia (USD$ 100 per unit according to the website)..

The thing is, I think majority of the drivers here are not fussed about their accuracy of the speedo being off by 3-4%
