Looking at the Supra Survey reward period December to June is a long time to send this livery/car to players. Especially, when it's only going to players that answered the survey. Whic. Probably aren't the complete GT Sport player base.
The survey itself was only a month and a half. Wonder why such a long time for the reward period. I'm sure they have the data of who bought the car and participated in the Supra Cup. Must be something else to it.
A redeem code? That would be out of the ordinary for car content.
An Add-On in the PStore? Maybe, but still out of the ordinary. We get Birthday cars in the same vein as a DWG.
If the servers can update all PS4s, I'm sure it can update just one car as we've seen in the past. Oh well, one week to go.
