Hi,

My 83 300D has a few rust spots here and there. Nothing that seems too serious, just a few spots of bubbling up under the paint, none much larger then the size of a silver dollar, and one of the welds on the body by the back rear bumper seems to have cracked slightly, thus cracking ther paint and allowing water in, rusting slightly along the seam.
What I would like to know is can rust like this make the car unroadworthy? I do indeed plan on getting it fixed, but I just want to be cautious. I dont want to end up spending a few $K on repairs to find that the body will never last. I have spent $1000 on general maintenance and will spend about that for a bit more maintenance and a few parts to be replaced. It s no big thing to me as I think Ill get lots of good usage out of the car, but I just want to know about how cautious one must be with a car that hasd a little rust, so that it is safe and roadworthy. Of ocurse I see lots of rusty cars and trucks, and think nothing of it, but its better to be cautious...
Thanks
