First look: 2014 BMW M3 and M4

McLaren P1 almost sold out

Fortunately – for McLaren are a bit stretched non all fronts at the moment – it seems that history isn’t repeating itself with the new McLaren P1 as reports today suggest the P1 is all but sold out. Autocar are reporting there are just a handful of the 375 P1s left to sell, with the P1 allocation for America, the Middle East and Asia already sold out and just a handful of cars left for Europe and other parts of the world.

But you’d be wrong. Those photos were in fact of a disguised SLS Roadster (although you’d have to look hard to see what was hidden).
