Carnation is a second hand car selling company. It is my personal experience that I am sharing with you. According to my requirement, I have approached one of its office to buy a car. I have chosen one of its car randomly to get to know that is the engine work is done or not. When I have opened the bonnet and checked the engine seals, I found that engine work has been done on it. I have my regular car mechanic with me, who also said that engine work has been done to the car. When I have moved to next car, I found the same. And not in the single car but in maximum cars.
Also, the price of the car is very high as compared to other car dealers. I supposed that the price would be negotiated according to the condition of car, but that was not so.
