They are both great cars. If you are jonesing for more power while driving a base model you will soon be jonesing for more power with the S. It never ends. It's not the car that feels weak. It's the driver.
What privileged lives we lead that so much energy is spent on which Porsche to buy while others around the world are facing genocide, famine, Aids, abject poverty, civil war etc. Be thankful for what we have.
