Imagine the rust underneath that you can't see!!! Up here in the Great White North lots of folks get undercoating before they take delivery or shortly thereafter. I have used Krown rustproofing on my '03 Sportrac since new. The under carriage and body panels are still like new. The downside is this stuff is messy and it seeps out for days after each annual treatment.

I will try and take detailed pics of the parts once they are removed. It will be a week or two.

Okay so it when in this week. The rust wasn't as bad as I thought it would be, but still pretty bad for a car with 9k miles on it. These were taken with my phone so the resolution isn't that great.

As compared to...? Rust is time based not mileage based. Do you park your car in a damp area or live on the coast? A good quality rustproofing product should inhibit the rust your Z is experiencing.

Compared to any car. Aside from the desert southwest most of us experience rain and damp conditions. The rest of the car is perfect, these two are the only rusty parts.
