Dodge Avenger Preview – 2007 Detroit Auto Show: Call it a polite Charger. Debuted at the 2007 Detroit Auto Show and due to hit US streets in late spring of 2007 with a base price of $18,895 (including $675 destination charge), that’s exactly what the Avenger is. Despite the Charger-esqe attitude of the sheetmetal, this is really a front-drive Sebring twin with the same guts, save for a more performance-oriented ride with the R/T model.
