Camry: none. At least there better be none.
VW: it's getting there, mostly just sheetmetal, although the struts are getting very crusty. 8 years of NH winters. I need to get the front fenders replaced (under a recall), but also need a door (I think it was badly painted from the factory), the rear hatch (pinch weld, somewhat common), and then could stand to have the leading edges on the hood and just above the windshield, due to rock chips. The worst that worries me is the rust just starting to show up on a rocker panel; I'm worried about what lurks behind the fender...
I don't know what the dealer will do for me (12 year rust-through warrenty) -- probably not much -- so I'm hoping I can find a decent paint shop that will fix the rust to my liking (not sure I want to tackle or not). You know, fix the patches "good enough" to look ok from 10 feet. Color blending would be nice, but is it worth it on an 8 year old car that is just going to be driven through a number more winters? I just want to keep the rust under control, and preferably have everything worn out at the same time.
