I have a 2007 Toyota Yaris. I have absolutley no problems with it. I love it. But I was just thinking of getting a Newer (2010) car. Do you think I can exchange it for like a Prius or Maybe get another car from another dealer (for example: Ford Mustang)? How much do you think my 2 year old car is worth? My car still looks brand new and its for the most part very clean inside. Do you recomend exchanging my car?
