check to see if the door handles are still in tact. A lot of times, the springs inside pop off so when you pull on the handle to open the door, that handle doesn't pull itself back in place.
Check for the A/C vents. they tend to snap and break easily after years of being beaten by the exposure to sun. Other than that, the engine should be solid. The 1st gen TL is the only generation that was built and assembled in Japan.
Almost done modding my car. =oD
