Should Your friend Replace Stolen Parts?  

Since he/she is your friend you cannot per se demand that the loss be made good but it is normal courtesy that the friend pays for the items that have been stolen.

I would think the friend would be nice enough to offer you money for the stolen parts but if he/she doesn't have the money for their own car, how are they going to pay you back for these parts?
I'd go ahead and turn these parts into my insurance comapany and see what happens there. but in the mean time go ahead and ask this friend for money to replace these items.
He or she should offer to pay regardless. That car was their responsibilty.
I hope it all works out for you.

I think they should. After all, they were driving the car at the time and I would hold them responsible. I don't think I should be the one to suggest it, either. I think it's a nice gesture on their part to replace them free of charge. Kathy.

If he is your good friend, obviously is because you lent him your car, he has to pay without telling. He cannot expect you to cough out the extra to pay for parts stolen. He is not a friend if he negotiate.

if he wants to pay for the parts though its not necessary but all means its okay for me. it also proves that he is not taking advantage of your friendship as he sees its his fault that's why it happened. if i were the one who borrowed from a friend and this also happened, i will pay for the parts even if he doesn't want to. i know how important a car to a person and since i borrowed it i should be liable to anything that will happen to it.
