[spool twice]

If price difference isn't too far off between CS and ZCP and GTS, and you can live with the trade offs, get the CS or GTS even if you plan on modifying it since they already have visual mods from the start that you may end up doing that will add to the bottom price of the ZCP:

-CF front lip
-GTS/CS hood
-CF diffuser
-CF spoiler (CS) or big wing spoiler (GTS).
-Alcantara steering wheel/trim
-Racier-looking door panels (if you like that sort of thing)
-OLED Taillights

All of those could add up, just throwing it out there especially if you plan on modding, I assume also visually.
