You can check under the hood for the shield before the test drive...
For the Japan built Camrys, usually the VIN# starts with JT###... And there is a little square on the front bumper (for towing or something like that).
Get the Japan built one if you can, it has better built quality.
Steering problem? Not that I know of. I know they have some tranny problems, but that's the V6 models.
Remember this: When you test drive it, just drive a little longer, to different areas (speed bumps, freeways, etc.) don't just stay in smooth roads, so that you can hear the rattles (if it has any), and to feel the power (if it hesitates or not).
