Average cost of repair of 1992 BMW 325i front quarter panel

What is the average cost to repair a 1992 BMW 325i front quarter panel. I was just hit this morning on the passenger side. The passenger door is a little difficult to open and the headlight is broken. The headlight on the driver’s side is also unseated and will not stay in place. I am trying to get quotes and don’t want to be taken advantage of.

It’s very hard to guess without seeing the car. It sounds like there could be more damage than just that quarter panel. I’d be very surprised if this is less than $1000, and anything up to about $5000 would be in the ballpark. Over that, I’d want to know why in great detail.
