4matic post production




Sure it's possible, assuming you have a ton of cash and access to a top quality automotive garage.
It would be cheaper to buy a second car with 4matic.
One example is that even the suspension setup is different. (So it was kinda hard to find lowering springs or coilovers for 4matic models)
If I am you, I would just do a trade-in for 4matic model
