Spec depends on what your requirements are.
If you’re only keeping the car 1-2 years and thinking about resale then you’d probably do something not far short of FE. You might omit Drivers Pack and Sports/Cup2 if it’s a daily driver and go with the base wheels. So a touring/GT spec.
For me, I want a foundation for some dynamics-enhancing mods. So just the base seats, which will probably get replaced with some Tillets or Sparco/Recaro from an Evora. I’d want Drivers Pack for the Track mode. Forged wheels and two-piece brakes.
I’d already selected a solid colour because I want Hethel Yellow. Black (no cost) callipers already picked. Maybe reversing camera and parking sensors.
Probably no surprise to anyone, I’d have Touring suspension.
Money saved versus an FE can go towards the exhaust upgrade and a Komotec 450 tune. So end up with a home-made GT450.
