I have owned many cars and was not really in the market for a new car, but Honda was having a lease special (only $199!!!) for a 2017 Civic Si and I couldn't resist. Let's just say I am very happy. I got it in Lunar Silver and I actually think it is a really good looking coupe. The rear wing does interfere with rear vision a bit, but certainly not a deal breaker. The car is a joy to drive, with great damping to soak up bumps and not be too harsh considering it is a sports car. It is quick enough to be fun, but not so quick that you're breaking the law in just 2nd gear. There is the expected turbo lag (and/or boost threshold) issue, but keep it under 3000rpm and you will get nearly 40mpg out of this 1.5 liter. As with most Honda manuals, this is a joy to shift. It is not quite Miata slick or nearly as precise as the S2000s I have owned, but still fun. It is not like the long, rubbery throws of VWs, BMWs and Audis I have owned. I am 6'1" and my head nearly hits the roof. Tons of leg room, but if you are taller than me, your head may poke through the sunroof (or get the sedan which had a bit more headroom). Seats are not leather, but are heated and I prefer that (GTI is the same). Leather is too cold in the winter and too hot in the summer. Stereo system sounds good and infotainment system works well. Who needs navigation when you have Android Auto? I thought I wouldn't like the lack of a volume knob, but the steering wheel volume button works quickly to turn volume up or down. This car will not be my daily driver (especially because it is a lease), but I will be missing it on the days I am not behind it's wheel.
I have had this car only 1 month. It has good power and I drive it mostly in Sport mode. Ride is somewhat stiff which is what I want and expect for a sporty car. Fuel mileage has been about 32 for the first 2 fill ups. The seats are great. Very good support and they fit my body and height. My previous 2 cars were a Prelude and an Acura RSX-S. The turbo has a totally different power range than the VTEC engine of course. Prelude was my all time favorite car. This comes real close and being just fun to drive every day.
This is the latest Civic Si, I've owned a 1985, and a 2002. I traded in my 2016 Accord coupe for this. So happy I did! Amazing value, nice bells and whistles, but it's still a civic. In the 2600+ miles I've gone, I'm getting 36-38mpg average, and that's in town! I've averaged 40mpg over long highway drives (doing 55-65mph). Not too powerful, but Sporty and Very Fun to drive! Yes it's a little smaller than the Accord, but it makes up for it in light, sporty driving with great gas mileage!
This car is a lot of fun to drive. I considered the ST before buying the SI. The deal breaker was the MPG. Let's be honest here, how often are you going to race? 0-60 is poor. The gas mileage is great. I average 38 between highway and town. The car has plenty of torque to pass once the car is rolling. Lack of clutch feel is the only real complaint. I hope for a larger displacement engine in the future with a turbo. Satisfied with this for now. Not to mention is is cheaper than the 2 biggest competitors, will hold value better, and cheaper on gas. Financially speaking, its the only logical choice if you still want to save money. Most likely will have better reliability too.
