What is the down fall on the SCION Tc?

I own a 2007 Scoin tC with a AEM cold air intake and a Magnaflow cat back and i would say the downfall is its weight and the fact that it is really top heavy. All that glass and that big sliding sun roof come at a cost and that is weight. I would not say that it is a true negative. I love the car and will never regret buying it, but if i were to pick two things that would be them. Other than that the car is great, I consistly get 30 to 32 miles per gallon on road trips and i get around 24 to 25 around town. Happy Motering!
