Bought these tires based upon Tirerack.com's reviews from Toyota Camry owners. So far, they have been a significant improvement in noise, ride, stability and handling over the previous Michelin Pilot tires. The 2003 Camrys (even the XLE models) are known for their road noise, and these tires help out greatly.
The only thing that I've noticed is that the car seems to be a bit slower off the line (this is my wife's car, and she is no street racer!). If that's the case, it's worth it for the improvements I've mentioned.
I used Tirerack's top tire installer in my area, and they were great!
