Rusting

I bought my Maruti Suzuki in Apr from Spectra. The doors of the car started rusting in six months and Maruti replaced all the doors in late 2007 accepting this as a manufacturing defect. The doors again started rusting after next six months. The obvious cause is that the new gates which were put were either not new or were not painted properly. Spectra motor tells me that rusting is because of the whether condition but why would a car always rust at one pirticular spot while the rest of the car does not get affected by wheather at all. I feel the product quality given to me was poor and Maruti should take responsibility of this.
