Wow.
That is below Vw dealer cost.
I'm not saying they won't honor that price, But I bet that is a pricing error that has not been caught.
Some places do a percentage off of list price, while some do a percentage above cost.
The flaw with doing a percentage off list is that big dollar items (such as that turbo) have such a small mark up that a 20% discount can take the selling price below cost.
I prefer to do a small mark up from cost that way I never have to tell a customer "I'm sorry I can't sell it to you at that price, but here's what I can do....)
You wouldn't like to see a price of $xxx.xx and have them say "Oh, it is actually $x,xxx.xx"
