Age, space, comfort.
Age- I am getting older, and so is the FC
Space- Now that I had a child, the backseats are quite useful
Comfort- No PS, AC or emissions makes the FC not too much fun. Add to that seats that slightly overweight people can't get into, and it is uncomfortable.
The RX-8 is not a slow car, and it handles VERY good.
Also, it won't remain stock. Who needs that crap
