I'm not in a large city, so perhaps my view isn't as skewed. Sure, if I look online I could find any car, and any trend within a group of owners and hate on them. When it comes to who I actually see in an 86 on a daily basis it's never any of those people.
I think you need to step back from the internet actually. That's likely what's pissing you off, not so much the 86ers you meet on a daily/weekly/monthly basis.
I've had my car for just over 2 years now and my insurance hasn't gone up at all. I'm pretty sure a 25-30K Japanese, rear wheel drive, sports car is going to fall into a specific category of insurance and the insurance companies have already figured that a bunch of idiots were going to wreck them. I don't think were going to see our insurance rates do anything super crazy, aside from the individuals who do stupid things in our cars.
As far as the civic thing goes. Our sales numbers peaked in 2013. Likely the sales aren't going to hit the same number this year as they did last year. The economy is still on the uptick, so it's not that. It's likely market saturation. The twins sold about 26,800 cars in 2013 (
http://www.goodcarbadcar.net/p/sales-stats.html). There were roughly 330,000 civics sold. Say 10% were Si's? (I can't find any data on the Si specifically) Likely next year there will be another 33K Si's sold, but the number of twins is likely going to be lower based on numbers through April. In 2012 the twins number was around 12k (but still 33k Si's likely).
My point is that this car is going to be a limited run. Think of it more as the modern 240 in comparison to who buys it. It's not practical like a Civic, it's not as pedestrian, it makes compromises in ways the Civic doesn't...it's just not the same car for a variety of reasons. Is it the same in the sense that people put fart cans on them? Sure...but now a days that's every car. /shrug.
Ease off the internet for a couple months, enjoy your car for the reasons you enjoy it, stop caring what other people do or think. You'll be better off for it.
