Had a bad experience with them from the word go after paying,that I was told thy Dnt have paperwork of the car(previous owner).I will get paperwork tht same week even today I Dnt have the paperwork.The car had a problem with the battery,thy had to take batteries from other cars until thy gave me one.. Went to the garage and the car stuck due to battery again...Got stuck due to No water on my way home and the sales man was like thy ddnt bloat or something to the car..After some days found out the car has a whole in the engine and in these rain, rain water getting inside the car and the sales man is not helpful because I remember asking him about the car problems and he was like no major problem, just the door n the car needs major service that all... Know am trying to communicate with the sales man and he send me the disc of some ada car wch is not mine and tell me thy is no paperwork...
