Before you go the route of buying it back and repairing it, make sure you understand the lien holder's requirements for insuring the vehicle.
Then talk to your insurance agent and see if they will provide the necessary level of coverage on a totaled and rebuilt vehicle to meet the requirements that you agreed to when taking out the loan.
I'm going to guess that once it's been totaled, even after being rebuilt, that it will be difficult (if not impossible) to get collision and comprehensive insurance coverage that will meet the requirements of your loan on the vehicle.
SF says the car is worth $23,000. At the time of total the current loan holder will be paid in full from the $23,000. That loan holder is satisfied and goes away.
For simplicity lets say our man still owes $15,000
$23,000 - $15,000 (pay loan) = $7,000 remaining going to our man, but...
$7,000 - $3,700 (car buy back) = $3,300 in cash left over to fix the BMW. Its gonna probably cost more than $3,300 to get it fixed so hes gonna take out an unsecured loan to get that money. It will have to be an unsecured loan because no bank will lend against a car that is still "salvage" or not legal to drive on the road.
But, if he owes more than $23,000...lets say he owes $24,000 and SF is only paying $23,000
$23,000 from SF - $24,000 (pay loan) = our man has to come up with $1,000 just to make the car go away.
That negative $1,000 + $3,700 (car buy back) = $4,700 will need to be borrowed just to put a broken car in his driveway. Then every dollar needed to put the car back on the road may need to be borrowed also
