Lets see the Xa has better horse power then the aveo, better gas mileage and will keep its value longer because it is basically a Toyota. It also has better aftermarket support. If I had 12,500 I would go with a Xa. Also I have driven one and they handle nice. Remember this is not the ugly box one. The Xa looks really cool on 20"s.
You got an excellent point there.... Toyota like honda keep the value longer than any other car. You can still sell a stock civic 99 for 12k and if I sell my nubi I only can sell it for 4k top, with all the mods
