Sweet car. My 2nd favorite color in a car is dark gray (Anthracite, actually). Ford is pretty close to that color. Just keep it until the wheels fall off. Add fog lights, painted mirror caps to match (so it looks like a Premium), and that's it. Everyone wants a GT, but consider that you bought a 300hp car for just a bit more than Corolla money. My last tank I got 27mpg. And V8 aside, it brings a grin to my face every time I drive it. For getting back and forth to work, it's ten times more fun, has more features, and I've actually gotten the tires to chirp WITH the traction control on. Manual rocks.
I paid $19K and change (got the fancy green paint) for a car that's this much fun to drive. Best deal ever in automotive history. To those lurkers out there reading this, get one now before the new ones come and ruin the party.
