I did the same I had an ST3 on order with a sunroof. The dealer that I had originally ordered form received the same color st2 with nave and sunroof. So I went and looked the car over last Friday and though about it for a few hours. I took the money I saved from the st3 package and put it towards the extended warranty.
I wanted the HID’s and the leather but like you I also like the non leather seats they will hold my butt in a little better when I take in the track.
Over all I’m still very happy with the decision to take the st2, the navigation system was on of the major factors for me picking the st3 in the first place.
My rides a 2002 SVT track car, & Boosted 2007 ST with the SAP.
The helmet has a special meaning for many drivers. How important is it to you? - It protects my head.
Do you have any special rituals when the helmet is concerned like many have? - I wipe it so that I can see better.
