Does not disclose damage on vehicle,refuses to compensate for damage

Absolutely pathetic,go in to purchase a demo vehicle that seemed to look like it was in perfect condition , ended up having more than a few scratches across the vehicle and a chip on the windscreen that was not disclosed before hand ,when enquiring about these issues on the vehicle I was told by the salesperson that 'if you are not happy with these issues I can sell you a new car' furthermore the manager states that having a crack on the windscreen is nit-picking on issues with the car?? I advise anyone looking to buy a demo vehicle to stay away from this dealership
