I'd suggest either the Westwings, or the eBay spoilers. The other two are just ricey looking and won't compliment the car well. I'd like to see the Westwings one on a G6. It might be too much though. I do think the eBay one looks good though. Just my 2 cents.
the ebay one looks good too!!! however, beware!! i have seen a couple of these break in the middle because people forget and shut their trunk by pushing down on the spoiler rather than the deck lid. after a while, they weaken, crack and break.
the "WingsWest" spoiler is a quality part that is very sturdy. i had one of these on my Honda CRX and it looked awesome. trick is to get the dimensions correct so that you aren't drilling into a reinforcement beam inside the deck lid but instead a 'flat' surface in order to mount it.
either one will look great on the G6. they both are superior to the aluminum and even the carbon fiber when it comes to appearance.....but then thats just MY opinion and you know what they say about opinions...... .
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".
The seller I mentioned, selling factory G6 replica spoilers, is now back online. Also selling G6 factory replica spoilers is a seller named AutoBoogie, or something like that. I bought mine from the latter before the other folks started advertising the G6 spoiler again. Mine came in Wednesday and I intalled it last night - around $220 painted to match and delivered.
I'm very pleased with the color match but it was advertised as no drill but requires drilling after all. There are six wing nuts made into the mold of the spoiler and all line up with the factory clearances on the underside of the decklid to make installation a little easier.
