UPDATE:
The neighbor stopped by yesterday afternoon advising me he purchased insurance for the Jeep and had inquired with the Insurance Agent about FULL REPLACEMENT if the Jeep gets damaged beyond repair.
The Insurance Agent quoted him the Blue Book ($7500) for the year of his Jeep which wasn't near the purchased price ($20,000).
The neighbors asked about replacement value of the added components and modifications on the Jeep to which the Agent said, "Give me a List".
This is where I come in.....
Neighbor asks if I would look a the Jeep to create a list of components.
I reminded the neighbor the insurance company may want receipts for the list of components and modifications provided; the neighbor said he will provide pictures.
My experience from years ago is the Insurance Adjuster wanted receipts.
Not sure I want to go to the trouble of creating a detailed parts list (some parts used are unknown) since I remember the last time I did this neighbor a favor.
