What do I think? A waste of money, but that's just because for my needs I rather put that money into something else, like thinning out that money into 911 ownership, 718 + another vehicle I like that serves a different purpose, OR a Cayman GT4
Beauty of getting a Cayman GT4, odds are it will hold value well over the years.
But as a serious track weapon this Cayman checks most boxes you can ask for.
To be honest, If I already had 718 any other Porsche for that matter, I would probably get one of these for a track beast, mass abuse car to really have a lot of fun with. But other than that, I wouldn't spend all of that money on it when I could potentially buy so many other things.
