I'm new to posting on forums so if I posted in the wrong spot I apologize. I currently have a 2005 durango SLT hemi with 147000 miles for sale and I was contacted by a guy with an 05 SRT 6 with 85000 miles for a straight up trade. To me it seems like a great deal. Does this sound too good to be true? What should I be looking for when I see the car in person? Any input would be great. Thanks .
