Co signed on a vehicle at Peoria Nissan for my sister in law because it was her first vehicle and she had not built enough credit yet to sign on her own. A sales manager named Christian assured me I could come back in about a year and they would refinance the loan in order to take my name off of the loan assuming payments were made on time after the year. On 10/02/17 I went to Peoria Nissan for a scheduled finance appointment to do just that. I was informed that they would only be willing to refinance the loan if we now traded in the vehicle for a newer vehicle which we were conveniently not told at the original time of purchase. Needless to say I will never do business here again with people that will simply tell you what you want to hear in order to make a sale and do not keep their word.
