I bought a 2015 Dodge Journey that I love but I took it back a wk later to get it treated someone broke the plastic on the bottom of my seat, this happened in July it is now the end of Nov I'm still waiting for them to fix it. Also I need $1200 worth of work done on it that they claimed the car was in great condition and it wasn't now they are trying to say it's because of MI roads, I'm still waiting to get it fixed. I'm just saying cross every t and dot every I before you sign any paperwork.
