No smart person would buy it, and you already know that. This is the second thread you start trying to justify to yourself buying it. If you want to buy it, just do it man. But most likely you'd regret it. If you can't afford a pristine example now, wait until you can. Buying a car with so much damage, especially when it has fragile aluminum subframes and suspension components is utterly stupid IMO. I can almost guarantee you not every single part that needed to be replaced was replaced, which is typical in any such accident.
With a few grand more, you could buy a perfect example, and most importantly, you'd get that extra money at resale. Something that WILL NOT happen with that other car. Good luck.
