Well I live in Tennessee and from what I have seen on the lots here you may have a hard time finding a Journey with a third row in the low 20's. I traded a 04 Explorer for my 4 cyl. FWD Journey and I love it. I get around 23 mpg (city- I haven't took it on hwy yet) and compared to about 12-13 with my V-8 Explorer I am very happy. The Journey drives and handles great. I feel like you get the best features of a car and an SUV rolled into one. Plus it is also pretty cool to be the only one in your neighborhood with a Journey. I think once you drive it you will be sold.
I would like to add a screen and hook it up to my radio also, but I was just wondering if something went out on my radio would hooking up the screen like you described void my warranty on the radio.
I have a 09 Journey SE with cloth seats and I am trying to find some seat covers that will work with the side airbags. Does anyone know where I might find some? Thanks.
