A non-sportscar has just as much "right" to have a body kit as a sports car as long as it is done in good taste.
It may or may not appeal to YOUR personal sense of taste but there is NOTHING wrong doing that.
Even a lowly Kia Pride can be fitted with a front chin and side skirts if the owner wanted it and if it looked good, then great for him. I wouldn't really call it "rice" as long as it is tastefully done.
Rice "gurus" ... there are RICEY cars and other times you are just plain overly sensitive over non-issues, which is may or may not result in the supposed "guru" taken as plain stupid or similar.
