I'm no good with cars and parts. So I was utterly confused. Lol after I purchased the trims the seller wanted to refund me and not send them I told them that I wanted to try and see if they'd fit. As their model selection process was absolutely confusing. When they arrived they looked identical to the ones on my car and my neighbours car which is a 2010 model. When I told the seller they fit he said that he was surprised. Got them for $75.
As I said most sellers have no idea and wreckers are worse.
I buy ECU's for testing & replacing for people and they want for the later models that take a E39 ECU $200 - $300+ for VE Commodore ones or I can just buy the Craptiva ones which are half the price and exactly the same thing as regardless they all need programming.
Some of them say send us your VIN and we will make sure it fits I just reply back don't worry just send it as I know it will work.
