Dragon models kits mercedes, porsche

Remember wayyyy back when Dragon kinda sorta sold car models? Me either :wink: I've been trying to track down, if these two kits were ever released. The street versions of the Mercedes Clk-Gtr and the Porsche GT1. Has anyone ever even seen them? Do they exist? I know there was a prepainted Mercedes in race livery and I think they had shared it with Revell AG. Then Revell USA got the Porsche as a kit a few times, same, in race livery. Thanks!
