An Aston Martin V12 Vantage S is perfect if you want to tell everyone you have a gentleman's car, but are actually kind of a lunatic. It's yellow, after all. So un-Aston Martin.
The people over at XCAR have driven it. It's a ridiculous car made even more ridiculous. Comparing it to your crazy relative with the great stories, who you're also trying to keep out of the family portrait, sounds about right in this situation.
Or you can just listen to it. That noise alone is just spectacular.
