You can completely transfer each piece of a full running donor car.
Problem with this is that on the scan tool etc. It will show the donor vin
Any parts will need the donor vin.
Not all parts bolt on, some have unique fitting.
Amg cars are not regular cars that are upgraded, they are literally buily separately from the beginning and any amg model parts production ends right at the model end span.
This is why you cannot buy a new crate amg engine for an older model.
A lot of real amg cars in pakistan are illegal ncp cars with tampered numbers.
