I drive 84 Cutlass daily, but not in the winter. I put 9000km's on it in the past 2 months driving to school (1 hour each way on the highway). I've got no rust, but the paint is horrible and at first glance you can't tell how good the car really is, but I still had some random guys in a parking lot the other day, asking to make sure I wasn't going to keep driving it in the snow.
My winter car is an 83
Caprice that's pretty solid and still somewhat shiny, I had a couple people last year almost mad at me for using it as a winter car. Crazy people don't realize how little these cars sell for. I couldn't buy a better winter car for $1500 than this one.
I put 100,000km's on the Cutlass just in summer driving over the past 4 summers and the
Caprice got 35,000km's the past 2 winters. Knock on wood, neither have ever stranded me anywhere.
