Really doesn't seem that bad to me either.

Everyone would prefer to have a rust-free car, and it's wise to avoid a car that is already suffering from it if you can avoid it, but in some areas and with some years/models it's almost impossible to find one that's totally rust-free.

In fact there's a good chance that if you don't see any in those prone areas, that it's already been fixed. If not done properly it could end up being worse than if you just purchased one with a little rust in those areas and either had it fixed properly or just took steps to prevent it from spreading.

My civic, for example, has a small amount at the rear quarters, but is virtually rust free everywhere else. The underside of the car is in especially good condition IMO. Compare that with an '86 Accord I used to drive that had rust only on the driver's side rear quarter (was wrecked there, that's the excuse I was given for the rust) and it was "fixed" by a body shop. After being "fixed" you couldn't tell anything had ever rusted there, but the underside of the car wasn't such a pretty site.
In the end, though that car is still on the road today, the repair work done to the rusted area ended up worse than before that work was done. Didn't take that long either.

BTW, shady visions, what processes do you plan to use for keeping that rust from spreading?
