My 1999 986
 

I just bought as 1999 986 when i turn on the it looks like a mist type of smoke comes out not always but the widows always steam up in rain.
Any suggestions or possible reasons.
Other than that I love the care it is awesome.

Smoke comes out of where? Exhaust? Cabin?

The steam on your Windows is a question for science. Outside temp vs inside temp. That's why the car has defroster vents. Set it to mid and windshield vents to get air flowing. The boxster has a small cabin, which is why you steam it up quick.

As far as your second question you need to search. There literally just was a topic about this. Right below this one I think. If you search and read what already has been answered and your question still has not been answered then post and make sure that your question is detailed and thought out in order to get the best response. This was really vague and that's why you're getting vague answers requesting more info.
