well when i see camrys and avalons driving down the highway and at every bridge joint there is excessive tire hop or when with 1 or 2 people in the back seat the ass end looks as if it will stuff the ground if it goes over a larg enough bump, or when i helped my friend replace is springs in a 99 camry (only 4 years old at that time) because of sag (oh and we had to replace LCA bushings at the same time because you could jiggle the shocks around freely) it leads me to believe that the quality of these products is of inferior quality when i have owned and operated various other vehicles of several different brands and not experienced even similar misfortune. I tend to think that in this situation it is not due to sheer luck that I have run across these experiences but more likely that they use cheap materials resulting in poor longevity and performance.... oh, i musn't forget that 99 camry had to have its cat replaced at 64k.
