A couple more pictures

As for a star rating... I would think probably 4? It was Lois Lane's main ride all 4 seasons, and it was used in one episode to crash through a door to "save" Superman.

First appeared briefly in 1x11 (Pheromone, My Lovely), but it was a 1993 Model with cloth seats. The one that was used for the rest of the series appeared in 1x16 as a '94 Laredo model with Leather seats and the "LL" Metropolis license plate.
