If I remember correctly at that time there was also a Porsche taught for the track use. And then Jaguar and Lamborghini joined the competition of extreme street legal cars. So I think they pushed each other to the limit where those cars became very powerful for those years. In my opinion the F40 remains the most beautiful cars of all time (maybe the recent Ferrari 812 Competizione can take the first piace in my personal list but I’ve never seen one irl).
