A car dealer sold me a problematic vehicle

I bought a car in September last year at the above mention dealer not knowing that the car they sold me is not in good condition.I drove the car for a month to an extent that whenever I drove long distances ,the car would not start on the way back.I reported to the manager of pre-owned with no luck.I eventually spoke to the DP.Furthermore as I continue to drive the car when it rains the is water coming inside the driver door as well as cold wind on the very same door.There are number of things that I am not happy with on the car they are as follows:Body paint is rough as if it was involve in an accident, old wipers making visibility to be very poor when it's raining, no spare key, no rubber mats, the car smelling bad, dirty on the inside, boot light is not working and the tail light not working.I have visited the dealer a number of times with no luck. As result I told them I don't want the car anymore and they might as well do evaluation on the car of which they were very fast to act on that.Although when mentioning the issues they were still very slow to attend to them.For me to be satisfied they must get me the same car same extras at the same price without signing a new contract
