I currently have a model S with the standard suspension (w/o smart air suspension option). I unfortunately recently moved to a new house with a very steep driveway and my Model S scrapes (lightly, but still - over time not great).
I've been in the market looking around for a slightly upgraded model S with smart air suspension. The price range I'm looking at for a used Model S similar to mine is pretty similar to quite a few M3 options.
How low to the ground is the model 3 compared to the model S? Does it have any suspension features?
