every time I touch my Vitara I find another part that needs replacing

just removed the front grille and found the lamp support panels are well rusted away. Anyone know of a Suzi dealer that wont charge me retail for these? do any UK dealers operate online? I have a Suzi EPC so can be completely accurate with part numbers. need some other bits n bobs as ever, trying to keep it up together...
I just got sick of the attitude from my local dealer E W Pichbeck's in Middle Wallop, Hants.
all suggestions appreciated. thanks Kev
