I am shopping for a used car. My 2005 Rendezvous is already giving me such a headache. I have a 2008 Town and Country which is fantastic. I am looking at a 2007 Pacifica Siganature Series. It has around 25000 Miles on it and it is AWD with the 4.0 Liter engine. It is fully loaded with navigation and rear dvd. They are asking $19000 should I buy it?
