What cars are the closest things to the GT cars in the Le Mans Series?

Anything other than the Japanese Super GT cars?

The M3 GTR is very close to a GT2 car.

If I've not messed up again the M3 GTR in the game is effectively a GT2 car because it was a GT3 car back in its time. I believe the M3's still running? Watched the Sebring 12 Hrs for like 2 seconds and happened to see it in the pit; what class is it in now in this ILMC thingy?

And to answer your question in the title, it's those cars that you see in Dream Car Series. You might say that's not "close", they just are! But they are dream machines so...
The McLaren F1 GTR however, is a GT1 car in the mid-late 90s which means...it's admittedly one class above any GTs that you see in FIA GT or LMS nowadays. So anything around 1100kg, 600 break horsepower, that'll be classed GT1 nowadays, and GT2 back in McLaren F1's time. (Or maybe LMGTS...gosh it's getting annoying!!)
And, I've probably said it various times, that due to regulations(especially about the chassis & aerodynamics) the GT500 vehicles' closest counterparts are the DTM vehicles with better tyres; a GT1 class machine could not match their laptimes in almost any circuit other than de la Sarthe/oval tracks which explicitly asks for more horsepower & less downforce; which means in GT5 they've got it somewhat wrong.
It's a bit off topic but better be tedious than to be unclear.
