automotive corrosion
(OP)
there're quite some questions which i'd love to ask regarding to the title. Hope you guys could help me out. where could i find the best resources of these?
1. which part of a car corrode the most? i.e. the bottom corner of the door, or even around the wheel. And why does it happen?
2. what is the best way to prevent the latter from happening? metallurgically or by coating?
3. any particular manufacturer in mind, which provides the longest-lasting car? Volvo?
Thank you.

The people who wash their automobiles often will greatly delay the onset of rust compaired to those who never wash their cars.

Other locations that rust a lot are anywhere that the standard protection has been damaged. Holes where trim is attacked aren't protected like the inside and outside surfaces.
I will say that lot has changed in the last 15 years. It used to common to see cars less than 6 years old with noticable 'edge' or door bottom rusting. Any more it is rare on cars less than 15 years old. My '92 Carprice was spotless when I sold it last year. My '96 Ford and '96 Volvo are both spotless (at least as far as rust goes). And this is all in the upper mid-west.
This is largely attributable to plastic trim (no holes and no galvanic action), stainless trim and exhaust, two side galvanized bodys, and better paints.

RE: automotive corrosion
Just off the top of my head; I recall corrosion of autos becoming a major issue in the 1970s when two things occured: (1) cars were made suddenly lighter which meant thinner sheet metal, and (2) a significant increase of salts to improve winter driving.
But as bad as things were around that time (including the many designed-in corrosion helpers), the auto industry has made great strides to improve. Autos today have fewer crevices, allow for drainage, and are optimally primed.
