no 1 can say abt design or aerodynamics.sum ppl like designs others dont.abt unstable thng,city is quiet stable @ high speeeds as compared to xli as i hav tried both.did 150km.h on both nd its a very high speed for family cars.
the only drawback in city is probably underpowered engine...rest it alright.
btw,what bad experiences u hav??
