It's recognizably a Mustang in some aspects, but there are some inaccuracies as well. 1. The dashboard should have two equal-sized humps in it, it's symmetrical on the driver and passenger side. 2. The wipers are backwards for a left-hand drive car. 3. There should be a panel gap to distinguish between the hood and cowl panel; wipers would never be mounted on the hood. 4. The cowl vents should be in front of the wipers. 5. The mid-height body line shouldn't run the length of the car, but curl downwards for the faux air-scoop behind the door.
The contours in the middle of the hood, especially the ones on either side of the center crease, suggest to me that this would be a '67 Mustang with a '67 Shelby G.T.350 hood, the rear end suggesting a non-Shelby car due to lack of integral spoiler or sport bar behind the front seats.
I'm sorry, but I'm a serious gearhead with a keen eye for the details; I can't help but notice all the little things, which tends to bug me when playing Forza Motorsport because even they don't get everything right.
Play [this song] instead while looking at this, and imagine hordes of zombies on the way and military trying to stop them by roadblocks and carpet bombings. Your point of view will change forever, slightly.
