Mustang cold engine startup
I feel I should point out, in light of how I've found this photo used, that this is a cold engine - i.e that's vapour/condensation not smoke!!
As far as I know this car is in excellent mechanical health, it was certainly very well cared-for. In fact, I saw a new-born baby seal suckling on its tailpipe and the lil' fella was doing just fine.. :o)
