Anyone get thick smoke out of tailpipes shortly after delivery?

So today I picked up my car at PCD - drove great! However - up in blue ridge mountains I stopped at a lookout and noticed a small amount of white smoke coming out of tailpipes. Started car up a few minutes later and smoke got

Really thick for about 1-2 minutes - freaked me out!! It then went away completely - drive another 50 miles with no more smoke. Also - control messages always said all systems ok - no alert messages ever came on and engine oil level was fine.



Any ideas as to what that smoke was caused by?
