This is one great car. I previously drove a 2000 Accord V6 coupe. My Civic Hybrid is quiter, more solid and refined than my V6 Accord. It looks great, handles well and is fun in its own geeky way. Driving this car is relaxing in that you focus on getting the best MPG possible, rather than racing from point a to b. Of course, it takes a bit longer to get to work driving 70 rather than 85 (which is how I drove the Accord), but that will change when the carpool stickers arrive (California thing).
The quiet interior. External temperature gauge. But above all...the great gas mileage! I'm getting 48MPG on my 100 mile a day commute, doing 70MPH...including up some steep grades!
An adjustment lever for the driver seat's lumbar support. Move the parking brake a bit inward...my leg leans against it (not a deal-breaker at all). Rear seat armrest.
