Two possible problems with that though:
1. Such easy performance can get boring quite quickly. It's superficial, effortless, and repetitive. The GR86, like the GT86 before it (and other more modestly powered cars, particularly older ones) take time, effort, persistence and skill to get the best out of. The tactile, organic pleasures are available more of the time.
2. There's very limited opportunity to use some of these high powered instant ready mix performance cars without landing yourself in trouble. Plus other road users will think you are a dick. Just think of all those RS3s and Golf Rs and A45 AMGs tearing around lane swapping on motorways or racing through city centres popping their ridiculous exhausts on an otherwise pleasant summer's evening. Everyone thinks they are dicks. Even they think they are dicks.
These simple principles apply when considering GT86s and MX5s. What the GR86 brings is (just?) sufficient power and performance to enhance the experience even further.
