Selling accident damaged vehicle and not disclose it with me before purchase

<p>Hi...on 17 December 2015 I purchased a 2013 Renault Megane RS265 from Imperial Select East Rand. When viewing the vehicle I asked the salesman is the car is accident free and he rep**** 'yes...it is a accident free vehicle '. After owning the vehicle for about 5-6months I noticed that the one wheel is repaired and that the passenger door is a darker colour on certain angles and especially at night when a light shines on the vehicle, but I ignored it. On 26 September 2016 I noticed that the previous owner posted a photo on the Renault Owners of South Africa page on Facebook. I came in contact with him and he notified me that the vehicle was in a rear end smash. He was standing at a robot when a woman drove into him. He also send me all the proof of the accident, photos and his insurance evaluation forms. I then went to the dealership on 1 October 2016 to confront them about this situation. The manager came out and looked at the vehicle and in a very rude manner he told me to send them all the proof,then we can take this case further. I send all the proof to the salesman I bought the car from and he send it to the manager. I was instructed via email that I must come in contact with the ombudsman about this situation but it will take about 4-6 weeks according to the ombudsman to get things going...so I don't want to take that long to settle this. After seeing the photos of the accident I don't feel safe driving a high performance vehicle that could have chassis damage to it...anything can happen at high speed with a vehicle that was in a accident. My life might be at stake driving this vehicle. I have all the proof of the accident and you are welcome to give me a email address I can send it to so that you guys can have a look at it. The number for the dealer is ********** and the managers name is Dirk....salesman is Kobus. What I want out of this situation is that they must take back the vehicle and pay me back all my monthly installments to date,or take back the vehicle and source me a new one at the same price I paid for this one...even if it is newer and more expensive. Please help me about this as I'm a very passionate car ***** and my cars must be in the best and safe way to get around. Very unprofessional not to disclose all faults on a vehicle to the customer and he must pay full price on it.</p>
