damage cars instead of a car

right now i have actually been talking to some off lease only sales ppl and i have had wonderful customer service so far but i have not bought the car yet... now i see sum bad reviews but viewing how many cars they sold in the same months as the complaints i see says the odds are good... not everyone shares bad experiences but 3 times as much dnt share good experiences... i have seen the whole been in an accident thing and have been shifting thru them judging and they say i can test drive the car take it to a mechanic before i sign anything and i will but an auto check i am going to run that also only thing i have not thought of but at the same time i am heading to every-one's warnings
