Are you comparing a camaro to a lambo?
I mean, the z28 is like what you are describing but you hate that too. Part of running a good business is maintaining image. Imagine showing off your brand new ss with a big motor and no stereo or ac and cloth seats. That would discourage the uninformed buyer. Now show the same car with hid headlights, 9 speaker stereo, and heated leather seats. Wow, the uninformed can't believe how many features it has!
