Currently I’m comparing the C8 to the 718. A while back when my budget wasn’t as high I was comparing the Supra MK5 to the M2. One thing they have in common is that the Supra and 718 are the lighter less powerful cars but more fun and the M2 and C8 are faster more powerful cars. How hard would it be to get some extra horsepower into the 718? I have about anither 60-70k sitting around for upgrades, track days, and consumable costs so I have a bit set to the side to upgrade whichever car and give them a little more go. If the Cayman was more fun, better handling, and fast then it would rule out the C8.
