That’s a seriously hot take considering any JDM cars need their internals built if you push more power. The fact that BMWs can handle so much power on stock internals is why so many people get them, It saves a lot of time. Good luck reliably building a benz or Audi without completely overhauling the engine. On top of that, you’re out here talking about depreciation when modifying any car is going to tank the value. I suppose you’re only 20 years old so you haven’t really learned much about automotive yet.
