I would not tow the car home if someone offered it to me for free. I would tow it to a wrecker and split the parting out proceeds 50/50
See the thing about a Porsche that has not been well maintained is that there are
#1-the problems you know about
#2-the problems they didn't tell you about
#3- the probems no one investigated with a top down check.
#4-the problems you'll never get to because you spent all your $$ on 1-3.
I suppose I would go through the hassle if we were talking about a rare limited edition sports car. But that's simply not the case for this car. They made a truck load of them and many just sat in people's garages for Sunday drives.
Those are the ones you want to buy, not these.
See the beauty of someone waiting to save more cash for a used garage queen Porsche is that during that savings period the prices plummet but the mileage only goes up a little.
