BAD SERVICE FROM MANAGER

We purchased a Suzuki Celerio for +_ R89 000 but the Retail Price was +- R118 000 with 49 000 kms on the clock. When we asked why, we were advised that the previous owner, a lady, didn't want to pay for the 60 000 km service. We weren't given a chance to test drive the vehicle and we were only given the service book once we left the premises. On inspection of the vehicle and the service book, we discovered that the vehicle was in fact a car rental and there is previous damage what looks like a front end smash. When we approached CMH Honda - The Glen, we were advised telephonically that the Dealership purchased +_ 40 car rental vehicles and the car salesman would never had **** to us. When we took the car back to show them the existing damage the Manger hid away and wouldn't assist us?
