Coolant help....and advice -2007 328xi

Hey guys, I'm brand new here so a quick blurb about myself: I drive a tahoe and ride a speed triple. Growing up, my dad had a 7 series and I love BMWs. I'll be buying a new M3 in 2 years, but in the mean time, I have a question regarding a used 3 series.

A friend of mine has an '07 328xi with 100k mi. He has had no problems from it and has always had it serviced at the dealership. He just bought a new car and was planning to sell his 328. I have been looking for a replacement for my wife's honda accord, which I hate for various reasons.

So his wife was driving it a few nights ago and drove over something presumably large and concrete, but she's not sure as it was at night. Looking under the front end, the splash guards are all busted and the leading edge of the skid plate bent down. More importantly, there is a hose attached to a box on the lower, passenger-side corner of the back of the radiator. The other end seems to have been connected at a 90 degree angle to the middle of this horizontal (coolant?) pipe. The pipe is some composite and the fitting for the hose busted off. I take it that all of the coolant drained out from here immediately after hitting the unknown object.

So my questions:

Is this the return for coolant from the radiator to the engine?

I have found diagrams of a similar looking pipe on online parts sites called a "refrigerant pipe". How involved should it be to replace this?

If I'm able to get this car from him as is, for a good bit less than kbb, would it be unwise considering it did overheat once on the drive home?

Sorry so wordy...just want to paint an accurate picture

I appreciate any insight. Thanks!!!

Ah, so it's the heater return line. Thank you.

So what do you think about this deal if I replace that line and refill the coolant? Anything I should be leery about with this particular model?

Thanks again!
