Nice video!
As an owner here are my thoughts
The stick is great, the steering is great, the size is perfect, looks great IMO.
I do not find the ride stiff at all, I have had much stiffer cars and I think the M2 and M2c are more bouncy. 1M does slide around, but that is what makes it feel so raw IMO.
The only issues I had with the car is the sound was not dramatic enough for me, that was fixed with an exhaust and mid-pipe. My other gripe was the seats and that can be fixed as well.
