What is value of a pre-certified transferrable BMW service warranty worth?
I am interested in selling my pristine condition 2011 BMW with 30K mileage
and "premium package" options. The car was pre certified when I purchased it
and I extended the transferrable warranty to August 2016 or 50K miles.
When comparing this with comparable cars, what is the value of this that I can
add to the asking purchase price?
