Steering is number one for me followed up closely with wind noise. I wish there was a way to permanently turn off the power steering without having dash lights come on. I had a 2011 smart fortwo and the steering was amazing. It did not have power steering and it was never an issue. It did not weigh much less than the Mirage so I am sure it would not be a big deal to be without it in a Mirage.
