Love it
 The first thing I did was replace the ugly grille!  Now it looks perfect.  Performance is exhilarating.  Replaced OEM tires with upgrades and traction is much better.  Bought a fully loaded one with heated SW, navigation, etc. and glad I did.  Do 30 mpg on the highway, using regular on highway and 89 in town. Performs the same.  Definitely one of the best cars I've owned.  Great value!
