That is, if a part costs them $100, they mark it up at least 50% and resell it to you. That includes handling charges for acquiring and stocking the part itself. If you get an oil change you can't bring in your own filter and oil and expect them to install it for just labor cost. That's really not where they make money.

Having said that, a thousand bucks may be an unreasonable markup. Body shops often price parts for the sake of taking money from insurance companies. Customers don't complain and insurance companies recoup the money from us. I've often gotten better prices at body shops by explaining that it's coming out of my pocket.

Keep in mind that you often get what you pay for in car parts. In many cases, a generic part will cause woe. Do some research on BMW headlights and definitely shop around.

I think you're being scalped on the price, including markup.
