There is a defect on the passengers side drain on the support rail that will accumulate water and rust out the floor, the floor my 98' went had to get the whole passenger side patched.
I should sue Chrysler for the extent of rust under my car (not one mechanic i know has seen a newer model car with its floor missing) so rust proof it ASAP, it will help but my 02' was showing signs of surface rust in the same spot, so I sanded it down and bondo'd it.
I'm sure I have a pic of my floor somewhere in these threads, if not I'll post one later.
SORRY FOR REVIVING A VERY OLD THREAD!! But I'm very curious, was there any more information about this last mentioned rust spot? My car's rusting in almost every spot mentioned on this post and I want to know where to check for this last mentioned spot to see if my car is doing the same. Someone have pics where to look maybe? Again, sorry for reviving a really old thread
