It's not so much that the car needs the chain replaced as it is important to replace the upper guide rails. Usually the chain is just done because you're in there and have everything apart. If the chain snaps, $3K at LEAST. Plus, they should be done before 100K miles so you're on borrowed time. Ask where he's had it serviced then go talk to them and see if it's been done. He may be one of the kind of people who just drops the car off and if the mechanic thinks something needs replaced, they just do it, period.

Thanks
