Missing Airbag

[recklessspyder]

Went to the dealer today for a "healthy" check up. Dealer found that the front passenger door was missing an airbag. The car was in a previous accident before I bought it and they put a resistor in between the wires to trick the airbag ecu. Dealer wants $700 to put new bag in with harness. Look like I can get a new one online for less the $200. I've had the door panels off plenty of times so I'm familiar with getting my hands dirty. Once the airbag was installed, I would have to cut the resistor and tape up the wires.

1. Since this is a safety item....would you guys do it or have the certified dealer take care of it
2. I need to find someone to sue over this.....good luck though as the car was only titled by a leasing company.....
3. Any other thoughts? The dealer wants to check the rest of the bag at 2.5 hours...I'll probably let them do that too.
