Auction house confusion

So I am confused in regards to buyout max pricing. I have a car that I can only raise the max buyout to 600k. I go to the auction house and others have the starting bid at 2 million with a buyout at 6 million. How is this accomplished?

Thanks in advance.

added Parts/Perks on the car, possible that the seller is a higher ranked painter/tuner.

Thanks, yea finally found some info on this from FH3. Need to raise tuner/painter rating. So basically no point in doing auction house. I’m not the best and I’m not a streamer so I don’t see this going anywhere for me :frowning:
