Definitely, I think the Z in 'Nismo' trim has always been a hard sale over what I offers to a GT model. A 400hp auto Z34.5 would provide better value on the used market at least.
Still doesn't add up the list of sports cars you mentioned above which all pass EU emissions plus the Supra and Z4, however the new Z can't 🙆♂️
Had a pull with Scott's from DriveR old boosted GT86 with 340hp, I wasn't impressed.
