Dueck GM on Marine Chevrolet Buick Cadillac GMC

I thought this business made a really good deal with my mother. The next day she got a call and they ordered her to return the car and the deal was off... Why? Because there was a 4,000km difference in what she had told them her car had. Even though she said she was not exactly sure and they sped through the deal without double checking. This sounds a bit off to me. So without offering to make another deal they took back their car and basically kicked her out.
Friends, I do not recommend making a deal with this company...
