I am checking to see if anyone else has a base model GS 430. I have a 2001 GS 430 with no rear wing, no Mark Levison, no NAV. My car also has 16" alloy wheels that were standard on the GS 300. Does the GS 300 16" wheels have the 225/55/16 tires or are they smaller? If my car did not have the GS 430 badge, you would think it was a 300. I bought the car used over a year ago. I don't know what other options were available in 2001, but my car does not seem to have any options.

 

that's how mine came. I have wood wheel and shifter though. don't forget though, all 430s have HIDs & wood ashtray.
