I was given a Model S as a loaner while my Model 3 had some work done. Was very glad to get the Model 3 back. The Model S feels like a normal car in comparison. Felt like going back in time.
Similar - I didn't like the Model S loaner I had for 2 weeks - felt "too big" if that makes sense. Stupidly quick compared to my M3 SR+ but I felt there was loads of wasted space around the middle of the car etc (was a 16 plate from memory)
