How can you compare two cars for sale now, when you intend to buy a car in March ? Those two cars for sale may be long gone by March.
I'd be considering the suspension of these cars. Originally the FRS had different springs, possibly shocks as well, than the BRZ. Those early FRS models would hang their tail out more easily than a BRZ...meaning oversteer. Buyers of FRS loved that.
For the 2015 model of FRS, things were changed in the suspension department, so that the FRS would handle more like the BRZ already did.
I own a 2015 FRS. Wish I had an earlier model, like a 2014 FRS. That would be one year after the bugs were ironed out of both FRS/BRZ, yet this year FRS would still have the original suspension pieces...thus hang it's tail out more than my 2015.
Additionally, for 2015 models of both cars, the upper shock towers were strengthened, but I would not care about that...most likely done for those who track the car.
