Worst Experience Ever When Spending R736K

I recently purchased a car cash from Merc M2 city and let me tell you how my experience was...Firstly I was connected to possibly the most terrible sales person i have ever dealt with the persons name is David and is in your used car section. I was interested in a GLC ********** (which i ended up purchasing because my wife wanted the car) and he said that he would be able to do my price of I wanted to pay cash for the car, so the day after I went to visit him to finalize the deal only to find out he had **** to me and could not do the price i wanted, he did this to drag me even though i specfically told him that I would not want the car unless he could meet my price and to not get me to come in unless I got the price i wanted as i don't have time to waste. So I left my 2 month baby at home with my helper cancelled meetings and got Uber to drop my wife at the delaership to find out that David **** and wasted my time. After getting into my car and leaving i realised I forgot my licences at the merc office so I went back to get it and sense my wife wanted the car against my better judgement I concluded the deal with CASH. After picking up the car a few days later and driving it for around 5km's warning lights start to come on for the front light - and this is a demo car with 8K kilos. So I got home and called david and he tryed to convince me that it was a problem with the settings and not a problem with the car. I than spoke to the sales Manager i think his name is Jean ( sorry for the spelling) and he was helpful and told me to go to bedofrdview Merc to get it checked as it wasn't the setting's. I did this to find out the whole light had failed and was explained that this should of been picked up on the quality check before the car was sold to me!!! so it seems like no quality check was done.. So M2 merc organised to send me another car while i wait for the spare part to be sent so the repair could be done.. only than to get david turning up at my house and droping off the car and wanting to take my care i just purchased back even though this was not was agreeded on at bedfordview and than david was going to take the replacment car back as I would not give him my car and only after him amking phone calls did he leave the car and go away!!!

MERC FOR SOMEONE WHO HAS JUST GIVEN YOU 736K WHAT DO YOU THINK OF THIS....NEVER AGAIN...NEVER AGAIN..BACK TO BMW....THANKS FOR DESTROYING MY GIFT TO MY WIFE...IT WAS SUPPOSED TO BE SPECIAL EXPERIENCE NOT LIKE THIS
