Ran into a GT350 on Mexico highway late at night.
I think it was R as it had the bigger wing, I believe a red badge and was insanely loud- in a good way
From a 40-60 roll it was very close. But I could catch up and pull ahead when he got the jump.
I hit the stupid vmax a couple times but he had backed off by then.
I was also low on fuel and was just waiting for reduced power but luckily it didn't happen.
We both exited and had a quick conversation at a light expressing mutual admiration of each other's cars.
He was surprised by the overall ability of the M3.
I told him that if I could have fit comfortably I'd have a GT350.
So far one of my best experiences and more prof that the G80 is a monster.
