I never notice the pipes on Muranos low, but definitely wonder what Toyota's smoking every time I see a Corolla or Camry.
I also agree with Shnak and Stickshift. The Murano is about just as bad as the Camry as far as the low ground clearance and vulnerability of the exhaust system. Not only esthetically speaking, it is a serious mishaps (once you notice it), and even for a soft off-roader SUV you'd expect to be able to go to your fishing spot of ski resort without fearing loosing your exhaust on the first rock/pothole/snow drift you encounter.
I was pleasantly surprised by the Murano's ride and friendly interior. There are lots of storage areas, very good cargo capacity, that makes it an interesting family hauler or home depot shopping vehicle. My concerns with the CVT trans, mainly on the performance aspect and somewhat questionable reliability, simplistic AWD system (despite the 4-wheel lock which is a nice feature) and high price of the SE model which is the only offering stability control convinced me to look somewhere else. And the low hanging exhaust system too
...
One last note. The Murano is manufactured in Japan and the interior quality is light yeas ahead (IMO) of the vehicles made in Tennessee though the new Altima may finally fare better on this subject.
