 I purchased the Spectra5 for gas mileage reasons and it was a cute car.  It was great for the first 4.5 months - consistently 30 to 35mpg and the car was so quiet stopped or running.  After that I get 15 to 20mpg with no changes to driving habits, route traveled or where gas purchased and the car is a lot louder.  Service dept blames it on weather, car breaking in or just say they don't know and no attempt to look it over.  It started at the end of summer before cold started.  Make sure that you buy from a dealer that cares.  I should have kept my SVU - same gas mileage and no car payment.
