So my S85 is in the White Plains service center getting some stuff done to it and I was a given a VIN 11xxx P85 (not P85+). The loaner has coil springs, not the air suspension. Might be sacrilege for saying this but: 1. The coils make the car feel much 'tighter' than the air suspension 2. I think I like the coils better than the air suspension which makes the car feel more like a luxury car than a sports car.
