Hola! Can you post a picture of your car please, or find a picture of the same year in your country. That would at least give us an idea of what it is, and what the equivilent US model would be.

The steering issue can be a pain, I've had 2 aveos, and have NEVER gotten the steering straight. I think there's just too much play in the rack and pinion for the alignment guys to get it 100%. However, if the car is pulling under braking, that means you have a brake issue. I'd start by: making sure the brake pads, rotors, shoes, and drums are in good shape. Then bleed the brake fluid.
