I think this is subjective. Some people are impressed others aren't. It also really depends IMO on what cars you've driven/experienced before. Everyone thought the P85D at the time was amazing and such but I was only semi impressed. Coming from driving cars similar in time and acceleration really makes the difference.
I've been driving a RRS SCV8 and the 90D was similar in feel so we went with that. the 60D/75D is similar to the 2014 Q7 we had, no bueno and not for us. I've had people think my CLS550 was insanely fast but it's also because they drove Hondas.
Totally agree with what you've driven before could make a huge experience. I'm coming from fast cars with 500+hp and afraid of 60D which I ordered will only make me satisfied for couple months. I'm pretty sure 60D is good for a daily driver but I cannot stand my car doesn't give me the extra oomph when I push down the pedal.
