Ok so I been DD for a week. I love this car.
I had an S2K before this and trust me it's night & day for me. Much nicer car. Heated seats in this recent bout of snow in the southeast is a major plus
Plus when the top is down it looks 100x better. The top down on the Z4 looks like it's meant to be down. On the S2K it looks like an afterthought even with the cover on.
The sport package is nice too. Hurts your gas mileage but definitely plants your arse in the seat
. Hope you have been out test driving man.
Let us know if you've got any more questions.
