Exhaust Smoke on Starting

[eomak]

hi, just wanted to say i get same on my 54,000km's 03 boxster.I drove it some threw winter months and didnt really notice it much.It happen 2-3 times in the winter.Now i insurnced it this spring and seems to do it 2-3 times a week in morning start up.Puff of white smoke that lingers around the garage for about 30secends with no smell.Its kind a imbareancing cause u see this clean nice new looking porsche and then smoke comes out like it was a 1980's vechicle.
