The SLR5000 was an over-rated car with much potential wasted on the General Motors usual failing price, they skimped on components and as such they all rusted and the low carbon content steel used caused issues for owners until rectiied.. See Real Car, SLR500 will not appear.
In saying this, a number of poor souls have spent mega dollars on these cars to procuce real performance, but at what cost?? I say its their dignity..
I owned one once.. I am sad!
My SLR5000 is heaps fater than your Monaro Con...
