Marge is a sweetheart. Actually driving something like your Rambler makes complete sense. She will give you cheap transportation, never depreciate and never fail an emissions test. Consider this. I sold my El Camino today for 7800 dollars and bought a 2006 minivan last week for 8000 dollars. In 10 yeas the El Camino would be worth 12000 and the Minivan will be worth 650... If it is even still running. Buying a newer vehicle makes no financial sense.
On the other hand, We just have to have a place for those grand kids.
