> the main wiring loom was cut and Mercedes wanted an absurd amount of money for replacing it
Modern cars can contain over a mile of wire and some of the important wires are all laid out during early stages of manufacturing, making it difficult to get at them for maintenance. Some cars have better access than others, but if they were carelessly tearing the car down, there's a good chance you need to take off, rewire, and test every ECU in the car.
As far as I can find online, most repair shops ask for about $1700-$2500 just to replace the main wiring harness, including the cost of parts and labour. A luxury Mercedes will have more wires and more automated systems, so you'll easily end up in the higher end of that range.
With a car in such bad shape, I wouldn't want my company to try to repair that car either, not without a "this is a bad idea" surcharge anyway. You just know it'll never run as well as it used to and if you make it a standard practice, you know at least a portion of your customers will blame you for it because you put the "repaired" sticker on that car.
The profitability of the second hand used components market is a real problem. I don't want a future where you can't reuse the parts in a broken down car because of some hard-coded encryption key, but the theft situation is seriously out of hand. Sadly, I think the Volvo approach will be the norm in the future.
