Pretend for a minute your a person wanting to purchase either a s4 or a 335 (same price and same performance). Let's say this person isn't going to mod the car and has no clue about the tune-ability of each platform. Which car is more attractive? A s4 or 335? The s4 has more perceived value...add a ///m and various m parts to the 335 and now it's on par with the s4. "
