If you are aware and have been reading MF Ghost at all, the latest chapter has revealed what Kanata’s car will be, and in hindsight, I guess we saw this coming:
A Toyota GT-86 (pre-facelift).
Better buy those pre-facelift GT-86s/86s/FR-Ss/BRZs now and store them away before the drift kids try to track them down in the coming decades when the anime releases.
EDIT: Well, I didn’t realize that the raw scans are already up to Chapter 10, so I guess it’s been known for some time. Even so, might be wise to buy one now before the “MFG Tax” hits.
