Thanks to all of you for your great inputs. Any one of them could have worked but I have no intention of ever selling this car so I am opting for spending a little more now than a little now and more later.
My dad, may his Teutonic soul rest in peace when we were poor imigrants---"we are too poor to buy cheap".
If I ever have more money than good sense I may buy a new 911 but why get rid of this fun Porsh-a.
