I was eyeing the GTR at one point. The issue is you can only do the quoted 0-60 time in launch mode. If you use launch mode 3 times, then your warranty is voided. What on earth is the point of that?
If I bought an impractical car, I’d get a Porsche Cayman and turbo charge it. Porsche under powers that car on purpose, because the chassis design is superior to the 911. The Cayman is a true mid-engine car with a perfectly balanced chassis vs. the rear engine 911. The only way they can maintain the 911 price premium is to put a much more powerful engine in it. For $10k, you can make the Cayman beat any 911. That or I’d get a Ford GT just because it looks amazing. It’s super charged. You can add a turbo charger and get 1000 HP from it.
