@Nana's gone red
Your car "Lilly" is a beautiful Crossfire Limited! A limited has Silver windshield surround moldings, Silver side strakes on the fenders, leather - heated - power seats, silver engine cover, rear speakers and an amplifier.
Svengoolie is a Base model. Base models only came in black. Cloth seats, no power seats, no heated seats no fog lights, & the engine cover is dark gray. Basically the "no frills" model. Just the way I like it!
The SRT6 has a fixed large rear wing that does not move. They have mostly the same features as the Limited model, the engine cover is unique to the SRT6, the wheels have many more spokes than the base or limited & it has a supercharger on the engine.
There is also another model called the Special Edition. It's sort of a mix between the three other models. It's like a dressed up version of the base model. The wheels look like the SRT6 wheels, the windshield trim is black, silver side strakes, cloth interior, no fog lights, etc... I think they were only sold in red and were only made as roadsters.
Here are examples of the different models.
I hope that this was helpful,
