After I bought this car I found numerous customer reviews reporting uncomfortable head restraints and seats. I cannot drive my brand new Honda Fit for more than 15 minutes without feeling pain in the neck and back. Head restraints push too much forward and hurt your neck and it seems to be a problem for many of Honda models for 2009 and later.
with my neck in pain, I have no favorite features.
It sounds like you didn't take it for an in-depth test drive before you bought it. So, in other words, it's not really the car's fault. Also, you said you found numerous customer reviews AFTER you bought the car.
Sounds like, overall, no research was done before purchase.
