Watch thoes car dealers!!!

So Saturday afternoon my son wanted to look at a truck he found. So we go to Max Madsen Mitsubishi in Downers Grove. We test drive the truck and he loves it, we go inside and sit with the sales lady to talk numbers. We end up being there for 2 hrs negotiating numbers with the General Manager of the place. He comes out and hands my son the "retail purchase order " for the truck ask him "Do we ...have a DEAL!" My son says "yes" and they shake on it and the fact that my son was already pre approved for the loan, it was late in the afternoon and the credit union I work at was closed. All we had to do was cut a check for the truck on Monday morning. The General Manager said that was fine and we left thinking we had a deal! Just an hour later they text my son and they sold the truck out from under him!!! By the time I am done today, I hope that anyone that reads this and all the other places I am going to post it will think TWICE before going to this place for business !!... because at the end of the day... A deal is a deal, a hand shake is a hand shake and what is right is right!!! I hope they are ready for me because that is the biggest bunch of BS I have ever dealt with especially from a GENERAL MANAGER!!
