The 06 cars do have a difference in the HP as well as the exhaust notes, and a warranty is good thing to have. However for the most part these cars have been pretty bullet proff. I would not hang my hat on just the warranty issue, nor the low miles. Anything under 10K miles is still of good value.
I would love the chance to get you the best deal on either 05 or 06 car, have several in stock and more on the way.
Call me if we can have a chance at making you a happy customer!!
