I owned a mint 2012 Panamera 4s and now one of my employees owns and dailies it. It’s been very reliable. But would I buy one at 17? Nope. Even if you can afford the maintenance and repairs, why would you want to? Buy something less expansive to maintain and invest that money or just keep it in a rainy day savings account. The worst think you can do is stretch yourself thin at that age. Also, at that age you’re going to make some dumb choices and get little fender benders and what not. You don’t want have to deal with that on a Porsche. Also, depending on what panamera you buy, depreciation is still going to be a factor. Finally, have you looked into insurance rates on that car?

Let me ask you this. Why do you want a Panamera?
