Great Car!
 I bought this car (had about 18 miles on it) and the very same day drove about 800 miles in a single day.  I think a lot of the posters here exaggerate a bit on the gas mileage as I am getting roughly about 32 mpg before the fuel gauge starts blinking.  Not bad but that was mainly highway driving.  Drove it back another 800 miles and getting the same results.  Of course, I had the AC going on the entire time which can affect the mpg. The interior did not have really nice quality materials but what do you expect from a $13k car.  The engine was great and very zippy but also at the same time, extremely loud.  You can feel the bumps and roaring of the engine.  Overall, a great car.
