Thats about right... considering after the chop shop gets done with it that is what it will weigh.
I just remembered one. The Maxton Mile is basically a mile long drag strip in North Carolina that only measures your speed at the end of the track, I have a coworker that goes there sometimes. This kid came in with a typically modded SRT4 Neon and clearly said he figured his car could get at least 200mph.
Apparently the salesman at the dealership told my uncle his new 350Z would do 200mph.
I informed him it was a 315hp GT and that the new GT500 has 540 hp.
I had to glance in the engine bay and sure enough it still had the rotary in it.
Damn Daytonas! 
Worst part about it, was this guy was actually a mechanic who was working on a customer's car.
