helmut hit the nail right on the head. id steer clear. first if you notice, he listed the welds, radiator, exhaust, heads twice, i didnt really look to hard to notice that. prolly did it to make his mod list look longer than it is
second, if all the work was professionally done, why is the nitrous bottle installed wrong? if you mount a bottle sideways you are supposed to turn it so the pickup tube is to the rear of the car.
also i didnt see any real chassis mods, upper and lower control arms? battle boxes? torque boxes are prolly smoked, and you can get much traction with out control arms(just a shitload of wheel hop)

hell if youre gonna spend that kinda cash on a stang, ill sell you a coupe thats setup right for less and you can wax that gt's ass! seriously. pm me if interested

but hell if you want a nice daily driver, give him 5k tops!
