Almost no rust, only one small spot under the passenger side, just behind the transmission fluid pan. It saw a lot of IL winters, but when I had to drive in snow, I'd normally take it to the car wash and get the undercarriage sprayed within a day. Idk, I enjoy it for what it is, I just feel like it's beginning to cost more to maintain it than what it's worth for how much I enjoy it. I'd like something more reliable, fast and fun to drive, and I still love driving a Pontiac.
