There is no such thing as a corolla limited edition. You can get a Corolla CE, Corolla LE, Corolla S and Corolla XRS. Scion is a sister company made buy Toyota (just like Lexus) but only sold at Toyota dealerships. Scion comes in 3 models: xD, xB and tC. You can learn more about them at
www.scion.com. If you get a corolla you will have negotiating power (not much) and special incentives from Toyota Financial Services. If you get a Scion, they have what is called Pure Pricing, so the price you see on the sticker is the price you pay: No haggle, no hassle. Scions are the most equipped vehicle you will find for the least amount of money. If you have any further questions please feel free to contact me.
