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.
