The reason that people are attracted to the stealth model is that they want to accelerate fast, but do not want the bling that comes with the Performance car. 20" wheels come with low profile tires that are slightly noisier, less efficient and more susceptible to damage than the aero 18". Some people do not like the look of the spoiler, do not want the slightly lower suspension, and see no value in racing brakes. If you want the racing style pedals, you can get those cheap on Amazon.
The $6500 price difference is substantial, and if you don't want the performance bling, the stealth car is a better buy.
