Ask them, do you race your v8 everyday? Exactly! You don't need that power if the speed limit is 35,55,65, or 70. Who saves gas more? What do you know about 6 and 8 apart from engine size and hp? Who gets higher insurance? Honestly, most people buy an 8 because it's an 8 and that's about it. Some do buy them because they wanna race which is a valid reason. A lot of people are so unreasonable so just try to understand them. They don't know anything about cars except for numbers. It's a matter of preferences. You don't need to explain them your reason...you still have a camaro whether they like it or not.
