Worried about n47 chain on car im about to buy

[Gar]

I'd be the opposite if the cars priced right I'd rather have the chain put in myself at least then Id know exactly what was done and what parts were used and the exact date it went in buying a car under bmw warranty will have a premium and the premium in buying it will probably be more then the cost of having an Indy replace the chain

The car would nearly want to be 8 or 9k to consider buying it though. 2k seems to be the rate on here to get it done
