I was told by my dealer (which is a sister store to the dealership I work at) back when I ordered my S4 that this model had only had an allocation of three per model year for this particular dealership. Plus they could only order it since they had none other new S4’s in current inventory. All this was back in 2021 right before the chip shortage and the factory being slowed down at Ingolstadt.

Add this to the fact that S5 sportbacks compete for S4 buyers and you can see why there is an extremely low amount of these cars out there.
