If you buy a brand new car and you can pick any car you want. To you and many others, it's an obvious choice, there's nothing that really compares to it, until you sell it or trade it in, it's a one owner vehicle. You may not have assembled it, but you're the only one putting the highway miles on it. You're the only one who gets to drive it and let it loose.
