Avis sold me a damaged car

I am so disapointed,frustrated and feel wronged by avis roodeport.i bought a car(chevrolete cruze)from them.They assured me the car was in perfect condition and has been tested only to drive it less than 100km and got stuck.In the last 3 months i had this car it has been fixed in the engine for more than 3 times.luckily it is stil under warrant.I feel avis owes me because i told them i am buying the car for uber but instead the car has spent 30% time in the dealership or at home waiting for parts for fixing it.
