A lot of cars have the battery in that spot, and on some if you're persistent, you might be able to change it without removing the tire. It's not common for chrysler to do it, but a lot of other do it, especially luxury cars, and I think your avenger is from when mercedes owned chrysler so that might explain it.
It's a weird choice :x
Oki.
On another note, I got the new 3DS XL. It is fabulous~
And no, when I got it, I wasn't supposed to move or to repair the car nor to lose my job. XD
But anyways, the face tracking super stable 3D works pretty good and the battery is way better than on my old 3DS.
Majora's Mask 3D was amazing!
A great improvement from the original. Except for a couple misses. Like the rings of the beaver race that are so glitchy...
