There are two sides to this arguement.
Some will say that YOU brought your car to the show to be judged and that you should be prepared to take the compliments with the criticism.
Others will say that "Its YOUR car, build it how you want."
I am of the belief that both arguements have some merit. I have a 70 Charger that has factory stuff mixed with some modern wheels. I like the look, and I am rarely surprised when I hear someone say ..."Nice car, but it would look better with STOCK rally wheels." Thats THEIR opinion. My response depends on my mood at the time. Most often, I tell them that they can buy a Charger and build it their way, then I will tell them how I would have built it. They usually just walk away.
