SLR is not built alongside other cars in Stuttgart; it is built in SURRY, England. This worksop in the pictures is there(Mclaren) new technology centre, cost them 200 Million pounds. Corridors in the centre are so wide that they are called streets. All of these streets led to naturally lit Main Boulevard. Main Boulevard is full of all the medallions and trophies won by Mclaren and of course the F1 car is there as well.
As a customer you have the opportunity to go there and see you your car hand built by Mclaren technicians, and also you can see your car going through different tests.
