I wouldn't even consider it.
1. Better looking imho
2. Better interior
3. More comfortable.
4. More interior goodies
5. WINTER and AWD....hello?
6. Should be easier to sell down the road due to appealing to larger range or types of people.
7. More room for people.
8. IN my area at least, easier on insurance.
9. Too soon to trade, you'll lose your shirt.
10. MS3 is actually more $$$ then a speed 6 in my area, or at least it was a few months ago and I haven't checked since.
