bad service-failure to disclose

I bought a used car from the above stipulating conditions that certain items needed to be done, i was assured thr car was thoroughly checked via 101 report, on delivery of vehicle noticed a water cap had still not been replaced, advised dealer on horrid whine on the vehicle and the water cap and asked for cooy of report, still not received. Took vehicle to be checked at a reputable service centre, wheel bearings dry and basically ceased..had to be ground out, brakes on the minimum and cambelt worn and cracked. The cambelt was one of my first stipualtions fir sale. I have now spent an additional R4000 repairing and replacing i have contacted the dealer who is now avoiding me and taking no responsibility.
