Yep, traded my Si sedan for the Hybrid. The thing I miss most is the nav. I commute approx 25 miles to work in the crappy Phoenix traffic. This is my first automatic in quite some time and I am really enjoying it and so does my wife since she doesn't want to learn to drive a manual. The gas mileage and the tax credit is a plus, but the most important thing to me is being able to drive in the HOV lane by myself. It has shaved about 15 minutes off the morning commute and more than 30 off the afternoon commute. I am a bit older than most on the forum and to me time is valuable.
I think the only mod I am going to do is get an Si front grill and call it a day. I had no plans on modding the Si and I will do very little to this car. Please don't reply with a "this thread is worthless without pics" commnet because if you want to see what it looks like, look at other threads. It's completely stock and very boring to look at. There is no driving excitement with this car. And, I thought my Si was bad with no torque...
I have been an asshole to the guys/gals that are getting tickets driving solo in the carpool lane. I am always finding myself honking and waving as I drive by and I have gotten "the bird" on more than one occasion. I haven't really had a chance to see what kinda gas mileage it will get as I have only had the car for a week now.
