What is difference between sport and base model? Is there "sport" badge?

 

car5car, there is no "Sport" badge that I am aware of. So, you can scratch that off of the list.

As for the difference between a sport model and your base model is as follows:
-1.4" drop from the factory
-1 step up from the standard rims in size (ie, when 16" wheels were standard, the sport got 17's, when 17's were standard, the sport got 18's).
-different interior detailing (bolstered seats, seats had a different design to them, some sports got a gray birdseye pattern vice the brown stain treatment in all the other cars)
-color matched trim pieces (ie, corners, grille, trim piece above license plate

That is about it. There was nothing upgraded in the way of the motor, braking system or other mechanicals that made the sport faster than a base model.

 

Thanks! No trunk spoiler?
Well, if there is no Sport badge, I will just install "V12 turbo supercharger nitro"

 

car5car, the spoiler was an option on the standard model where it was standard on the Sport model. I seem to also recall that the sport model got a different looking spoiler, but it wasn't that big of a difference to be like "oh wow, look at that thing".
