There was a dealer on Ebay selling spoilers for the G that looked exactly like the factory spoiler, which IMO, looks the best.
The only problem? They were coming out of, or thru, New Orleans. I ordered mine the week prior to Katrina coming to town and never got it. If they come back on board with the G spoiler, I will be getting that one.
$235 painted to match the car, delivered, and it looks "factory".
