2 not 7

[Daisydo]

Hello out there I've just joined this site,hoping to get some advice.I bought a audi tt in 2019,from a well known dealer in Cardiff. I thought id'e found my dream car and at that time i had come out of hospital or a few hours with my parents,plus I thought I was getting a good deal because it was cheaper than the first one i had seen at another garage that day,all the same speck just this one was cheaper. To my surprise sales guy informed me it had only 1 owner so I bought the car. Now I need to sell my car, never thought I would be told it had 7 owners not 2. I would never had bought the car if Id'e known it was 7 not 2, Please give me some advice.
