I did some digging on this Legion (the dude behind the Donkervoort D8 GTO) and found his blog with a whole bunch of vintage tracks on it, most of which are new to me so hopefully new to you too. Imola pre-'73 I've already got as Imola '72 (but this new one seems to have better AI), and the historic/vintage Monacos have appeared before, but others I've never seen. There are new layouts to existing tracks too (eg Bilster Berg, Zandvoort). A few of the tracks are really quite good. Historic Laguna Seca is an acid-trip disaster, and don't drive Stardust in bright sun if you value your eyesight, but tracks like Adelaide, Lime Rock Mountain, and Warwick Farm are pretty good.

He's BoP'd a few cars on there too.
