This story bothers me at several levels. First, if you were doing 176 mph the night before and only 20 hours after you got the car someone hit you the next day, that means "the night before" you must have just picked the thing up when you went out on this supposed 176 mph run. Do you have any idea how much open road you need to reach those speeds? Do you have that kind of road available? I doubt a local racetrack was open and available for you to do your "run" only a few hours after picking up a brand new car. And doing those kinds of speeds AT NIGHT at ANY location without appropriate lighting?? I'm sorry but if what you say is true you're a complete idiot. If you were in fact driving it that fast right away you were already in the process of destroying it; you were an accident looking for a place to happen and this guy who hit you just made it sooner rather than later.
Since the car comes from the factory with a limiter that prevents speeds above 158, am I to believe the first thing you did the night you got your car was pop the hood and disable the limiter so you could start thrashing a brand new car without properly breaking the engine in? Did you plan to even keep this car driving it like that? Even if you just did the factory limited top speed that's still insane on public roads, much less on public roads in the dark and just indicates a profound disregard and disrespect for not only other people and their lives and property, but for the car itself.
If you think you are being "cool" by claiming you drove that fast on public roads you are an absolute flaming idiot who is not only going to kill yourself but unfortunately you may very well kill other completely innocent people. What you are claiming is NOT cool; not now, not ever. If the insurance company happens to read this thread they'll either likely dramatically raise your rates or just drop you completely. They may even contact the police and have them read this thread since you've made a public confession and they know the identity of the car, they know who you are.
I'm truly sorry to see such a beautiful car destroyed but so much of your story just doesn't work that I don't feel sorry for you. I'm afraid I'm going to have the raise the BS flag on this one.
