Sorry to hear that mate, your hard earned $$$ to these scammers makes me furious..
i too have heard alot of dodgy stories about this "place", im guesing alot of people have.
They are known to perform backyard makeshift mechanics to pass a car off aesthetically appealing then you drive out the driveway or 2 weeks later and the rubber bands holding your bodykit snap etc.
I nearly got conned on a car from another import dealer in that same area....luckily i checked over the engine bay and found the compliance plate had been drilled off, they had a manfucaturers plate that looks similar to the compliance in the same location to try and pass it off. Real dodgy.
best advice is to steer clear from these dodgy c**t import dealers, if u do decide to buy one from em get a full inspect and comb over every inch of the car
