I don't get the association with Lime Rock? At least make it lime green then!
As mentioned you can just build one yourself and then get yourself a plaque made - 201 of 200!:
If you take a base E92 M3 price of $60,100 (excl sales tax, destination and gas guzzler tax), Individual paint $5,000, Competition pack $2,500, Carbon leather trim $500, carbon front lips $750, carbon rear spoiler $550, M Performance exhaust $4,000, so far we're at $73K. So as a package its a little cheaper, but you could likely negotiate a better deal on an individually specced car than 1 of 200.
Expect to see another special edition before the year is over though.
